Through a couple of auction sites I’ve been able to piece this puzzle together a little further. There was in fact a company in Denver, Colorado that specialized in leather goods and trunks. The building still stands today.
To date I haven’t been able to find a photo of another trunk that’s the exact same as mine, but we aren’t far off. I’m glad I at least have the company sticker as a clue, but I wish my trunk had a travel label on it that indicated a voyage on some fine vessel, such as this one that traveled aboard the S. S. Empress of France”.
This photo of one of their delivery vehicles is by far my favorite find from the research process.
