Vintage Barbie accessories are always fun to find! This black plastic tray feature's the fashion doll's name right in the middle:
We believe it to be from the 1960 Friday Night Date outfit and accessories (#969) or the 1964 Leisure Hours package.
It measures 3-11/16 inches long by 1-13/16 wide. It is in great condition for having been used, with a few minor scratches on the bottom.
