This is a lot of 3 "Kiddie Car Classics" tent cards made by Hallmark.
The cards are brown and feature indents and slits for folding and staying in place. Two of them are for the 1955 Murray Fire Truck, and one is for the 1955 Murray Fire Chief.
They measure about 5.75" long and 3" wide when laid flat.
These items come in very good pre-owned condition.
