6″ vintage, plastic Tupperware doily.
There are still 3 available. Each is in very good condition with no breaks. They are not stiff and bend easily. They were actually still in their original but opened packaging.
Each still has it’s oval tag attached. The tags have “Tupperware” and the copyright date of 1956 on them. However, I feel the doilies were probably produced in the 1970’s-’80s.
