1920 Homecoming Panorama

Measuring seven-by-24 inches and most likely still in its original frame, this large three-piece panoramic photograph came to the Heritage Center from University Communications photographer, Casey Cass. The Cass family has quite a legacy at CU. Casey’s father, Alan Cass (A&S ex’63, HonDocHum’99), is the head of the Glenn Miller Archive and his grandfather, Claude Cass, worked as Macky Auditorium’s director and stage manager for several years. Claude later became one of CU’s chief building engineers and part of the team that constructed the 1953 Folsom Stadium addition.

When Casey dropped by the museum he had no idea what event the photograph pictured or even why his grandfather had it hanging in his office for years. His best guess was that Claude enjoyed the image, especially since Macky was in the background. That was all the information we as a Heritage Center staff had to start our research, and we were eager to figure out what was going on in the image.

The print shows some kind of significant gathering at Gamble Field, CU’s first football, baseball and track field near where the UMC is today. Due to the number of people on the field and in the stands, we were unsure if this was a sporting event or some kind of demonstration.

So I put on my detective’s hat, grabbed a magnifying glass and took a very close look to see what clues the photograph might reveal…

The first thing one should do when facing a new mystery is to take a close look at what is in front of them and determine what initial questions or observations come to mind that could provide clues. My first question was when did this event take place? Without an idea of the when, I would be unable to find out the who, what, where and why.

When investigating a photograph, one must always turn it over first to see if someone wrote some identifying details on the back. As I took the matted print out of the frame I quickly realized it would not be my lucky day. The only legible pencil marks written on the back were “Return Photo in Good Condition,” “8415” and what looks like “Slick Sat 10/8.” None of this information was helpful to me.

Since I had nothing that might hint at a date, an event or even a photographer’s name, focusing on the cars seemed to be the simplest second step. My initial guess dated the cars from the late 1910s through the 1920s. Having learned a few things from my vintage-car-guy husband I felt comfortable with the general time frame. When I saw the two license plates, however, I knew I could do a better job zeroing in on a year. By doing a quick Internet search I was able to narrow the date range to 1919-1920 based on the style of the plates on two of the cars in the foreground.

While I scoured the photograph for additional clues, Annika, the Heritage Center’s collections coordinator, flipped through yearbooks starting in 1919. Wishing I had a slightly more powerful magnifying glass, I squinted far into the photo’s background and uncovered a marching band leading a procession of people. This made me quite confident that it was some kind of sporting event, most likely football. By the blurry details I could pick out, the band uniforms looked like the military-style jackets the CU marching band wore in the 1920s. I slowly scanned the crowds on both sets of bleachers and located a very small band for the opposing team on the left side. Now I was more confident that we were looking at a football game.


Notice the band director dressed in white at the far right with a megaphone resting on his shoulder.


One can barely make out the opposing team’s marching band, only the horns and trombones give them away.

After about fifteen minutes of searching, Annika brought me a yearbook. She found another photograph of the same event taken from a slightly different angle in the 1920-21 yearbook. Score! Reading through the football season notes about the different games, we felt that the photograph was probably showing a halftime event during the big state championship game with the Colorado Aggies (CSU). The game finished in a tie score of 7-7. With that tie and a win against the Oklahoma Aggies later in the season, CU took second place overall in the Mountain circuit of their division that year.

In addition to the yearbook, Allyson, the Heritage Center’s director, remembered a loose scrapbook page that she thought might connect with our photo. Sure enough, the page had a copy of our photo from the Colorado Alumnus (the early alumni magazine) pasted onto it. Apparently this football game was also the Homecoming game that year. This new information then led me to find an actual Colorado Alumnus article that detailed everything.

The game took place on Nov. 20, 1920 with about 10,000 spectators watching, a record attendance at that time! It sounded like a nail-biter of a skirmish with CU scoring late in the third quarter. CU fans were loud and enthusiastic for the entire game, often drowning out the opposing team’s band. A group of about 500 Boulder businessmen sat together in the stands and at some point paraded onto the field. While I have not been able to absolutely confirm it, this impromptu parade is probably what is happening on the field, especially with the marching band leading the train of people.

So why did we go through the trouble of deciphering this photograph? Yes, it is fun to undertake the detective work and to know what little slice of time this represents, but there is a bigger picture here as well. Museums use artifacts for illustrating an exhibit’s story and connecting visitors to the past in tangible ways. Understanding an artifact’s history and use can help you figure out how to tell the story. Now that you know something about this photograph, what types of narratives could you develop using this image?

As with most historical investigations, there are always questions to which you will never know the answer. One thing we will probably never know is why Claude Cass had this photograph in the first place and why he was so compelled by it to keep it in his office for so many years. While he did not attend CU, the 1920 census shows him as 17 years old and living in Boulder. Since the football game was such a major event, perhaps he was actually at this game and one of the young men on the field.
