Vintage toy children's teacup set orange

Description

We dug these up from our backyard.  There was a family that lived in our house for 38 years before we did; and the house was built in 1959; so it's safe to say they're not older then 1959, but I really have no idea how old this orange cup and tea cup are.  I've also cleaned them up as much as I could, but they were buried in a rainy, muddy backyard for a long long time.
