This Inge-Glas Old World Christmas glass fish Christmas ornament was made in West Germany from the original antique mold. It's number 7542, simply titled Fish, and comes with its original certificate in the original box dated 1983.
The 3-3/4" long fish is an unusual and pretty shade of periwinkle or violet blue enhanced with silver glitter on the scales. It's in excellent condition, as are the box and paperwork.
