This is a great picture of the building which housed Chris Von der Ahe's grocery store and saloon, at the corner of Grand and St. Louis Avenues. It comes from the August 3, 1958 issue of the Globe-Democrat and I have to Jerry Vickery for getting me a copy. From what I understand, the grocery was in the front of the building and the saloon was in the back.
I don't think the picture comes from 1958. If I had to guess, I'd say it was taken in the 1920s or 30s, based simply on the cars in the photo. Off the top of my head, I can't remember when the building was torn down but it's been gone for a long time and I don't think it was there in 1958.
