I wonder what this building was in a past life? It is on the corner of 31st and Judah. According to City records it was built in 1937. I don't find a photo of this intersection in the S.F. Historic Photo Collection. It looks like it could have been a grocery store, but I know there was a Safeway at 30th & Judah later. Hmm, now that I think about it, is the Gymnastics club in the old Safeway building? Need to investigate.
