Hallmark vintage intaglio etched birds crystal pendant necklace silvertone chain

This is a lovely vintage signed Hallmark Cards Inc. clear crystal pendant necklace featuring intaglio etched song birds love birds on a long silvertone metal chain with a barrel clasp. This was from Hallmark’s Little Gallery collection. The chain is 20” inches long (no extender). The pendant is 1 7/8” inches in diameter. There is a metal Hallmark Cards, Inc. brand tag near the barrel clasp. Very good pre-owned vintage condition. This would make a great gift!
