The Flintstones Happy Meal Toy Cars (Set of 2)

A set of two plastic toy cars featuring characters from The Flintstones. One car is green with a character wearing a black hat and red bandana. Another car is yellow with a character in a white cap. A third car is pink with a green character under an umbrella. The fourth car is grey with a character wearing red glasses and a red cap. Each car has multi-colored plastic wheels. These appear to be promotional toys, likely from a fast-food chain. The cars flip over to make the other 2 cars.
