Reminiscent of a simpler time, these pretty antique and vintage Valentines have the theme of bluebirds. Beautiful vintage and Victorian art that you can customize by adding your own text. Create your own holiday party invitations, send a "secret admirer" card, or add a message of love on the front and/or inside. Cards come in two sizes, with envelopes. Postcards have no envelopes. And don't forget the matching postage!
