The picture below shows a larger view of this Large Old Christmas Holiday Santa Claus Celluloid Pin Back Button. This pinback button is not dated but it is old. It has a colorful jolly Santa Claus winking head image. It is marked:
MERRY CHRISTMAS
The pin back button measures 3-1/2'' wide. It appears to be in excellent condition as pictured. The large front is clean, but there are a few small surface rust spots on the back.
