Thank you for your interest in this photo!
I did a little research. According to wikipedia, spam.com, and roadsideamerica.com, Spam was introduced to the public on 7-5-1937, so 1936 is probably not the correct date for this photo. Unless, could it be that Spam was sold in stores before it was officialy introduced? Other possible years mentioned were 1946 and 1953.
I am going to add some photos to the history thread that were almost certainly taken the same day. They were in the same area and the negatives were together in the box. I would appreciate any comments about the photos.
