Thanks a ton for all the research assistance! All I had was the photo dated October 1945, but it appeared to be an employee photo, not a grand opening. I had no idea the building would go back to 1929. It was my father's first job after returning from WWII, but I never know the location. I'm going to write this information on the back of the photo so my kids won't have to struggle with this down the road. Again, thanks so much for your help!
