"A young man walks past the "The Pup," a hot dog and hamburger stand located at 12728 Washington Blvd. in the community of Venice. The Pup is a small fast-food restaurant in the shape of a large white dog with black spots, sitting on hind legs, with access available through a door in his belly (center). Signs advertising colas and a variety of food items are seen on every side of the building. Houses can be seen in the background."
Circa 1940.
Chili-French dip over the 7-up sign. Sounds interesting.
