Vintage Find: Tea Cups (and snack plates)

Aren't these sweet? Although the leaf design is a bit, um, suspect, I had to have them. The colors of the leaves are so pretty- and the cups incredibly dainty. They almost seem suitable for a child's tea party. The man at the second hand store assured me they were snack plates for ladies' tea parties in the 50s. Whatever their purpose, they now live in my hutch, happily. Have you been thrifting lately?
