Fun, Kitschy metal trays were made for every state in the union and were popular souvenirs brought back from family vacations during the 1950's and 60's. They would  usually have a map of the state and corresponding information such as state birds, flowers or other related facts, much like this one from the "Keystone State" has on it.
Some were flat trays and paired with matching coasters and others, like this one had indentations to carry up to seven glasses without them sliding around.
