A reason to use snail mail

Have you bought your Marvel Super Heroes stamps from the Post Office yet? Last year, the U.S. Postal Service issued commemorative stamps featuring DC heroes; now the Marvel set has been released. I bought two sheets today: Ten stamps on each sheet of 20 are portraits of individual Marvel characters: Captain America, Elektra, Iron Man, Silver Surfer, Spider-Man, Spider-Woman, Sub-Mariner, The Incredible Hulk, The Thing and Wolverine. The other 10 depict individual comic book covers.
