Pepsi sign, part of my uncle's estate, was in the family general store. No idea of age. About 6" tall and 16" wide; plastic front and metal back with max 40w light inside (working). Identified on back as being made in Toronto, but can't read the company name. Could have been intended to either stand on a counter, or to hang. We have no idea about the age, I'm guessing mid 50's but we really can't seem to find anything online that looks like this. Help? Glen
