1987 Wildlife of Our Fifty States 22 Kt Gold Replica Stamp Mockingbird

Vintage 1987 Stamp Replica!

Envelope window under stamp is a little bent - sold as found. Stamp is in good condition still. The envelope itself hasn't been opened (that I can tell), but there is an insert about the stamp and bird inside. I'm too scared to open it.
