I believe around the 1920’s based on my research. The building appears to be a photo of the Barracks at Fort Knox (known as Camp Knox at that time). All pictures were stored together from an estate, so I assume they are all together. I would welcome any additional information, if you wanted to share your knowledge. We take all of our pictures of our listings. The item in the listing photos is the exact item you will receive. Please don’t hesitate to ask any questions. Thank you so much for looking.
