These are brand new 20 count "Forever" US postage stamps. They feature illustrations of five classic illusions: a rabbit in a top hat, a fortune teller using a crystal ball, a woman floating in the air, an empty bird cage, and a bird emerging from a flower. The stamp sheet features four of each design. Forever stamps are always valid with USPS for first class, one-ounce postage. However, these are no longer in print and they are ideal for the magic collector. 0231CBMARTMAGICSTAMP
