This is an unusual item. It was issued in Austria in 1907 to celebrate a local toy and doll festival. The festival was held during the Christmas season. The stamp is 1-1/2" by 2-1/8" and is a rich red that does not photograph well. It is in mint condition with stamp hinges attaching it to the card.
