Michael Hernandez de Luna
"Prozac," "Viagra"
Computer Laser Print/U.S. Postage Cancellation, 1996-9

The artist's pieces violate a number of laws. In addition to reproducing trademarked designs for Viagra and Prozac, de Luna has sent his artist stamps through the mail as postage. The cancelled letters are a testament to his skill in fooling postal workers. Many other works are featured in The Stamp Art and Postal History of Michael Thompson and Michael Hernandez de Luna.
