Vintage Four Decoupage Flower And Bird Eyeglass Lens Pins

Unique flower and bird pins created from decoupage and eyeglass lenses.  There are four pins in this lot.  I am told that these were a popular craft project in the 1960's and 1970's.  One pin is signed but I cannot make out the name.  A fun conversation piece, especially if you work at an optometrist or eyeglass shop!

Condition:  In excellent condition for craft pieces.
