Vintage brass bookmark with reverse crystal intaglio illustration of the nursery rhyme "The Cow Jumped over the Moon." The cow is dark brown with nice details to the head, tail and legs; the moon is a silver sliver crescent. The crystal disk is banded with brass flowers and swirls. This would have been charming in a child's book to mark the page. This piece is in very good condition with a little darkness on the lower point of the bookmark as shown. Measures 2 1/4" long; the crystal disk is 5/8" in diameter.
