Today marks the 40th anniversary of "Taki 183 Spawns Pen Pals", one of the first articles ever written on graffiti, published in the New York Times on July 21, 1971. The piece profiled a 17-year old kid already known by his peers as a king: Taki 183who said in the article, “You don’t do it for the girls, they don’t seem to care. You do it for yourself.

Taki 183 will be at The Hole Gallery tonight celebrating the big 4-0. With him will be Caleb Neelon and Roger Gastman, the authors of The History of American Graffiti, the definitive story behind the art form, with a forward by Taki 183 himself.

Co-author Caleb Neelon has painted walls in over 20 countries on five continents, has written a few books, including Graffiti Brasil and Caleb Neelon's Book of Awesome, and was editor-at-large of Swindle magazine. We caught up with him on the eve of the big party to hear about his newest book. Check out this preview and read his commentary on the pages.

The Hole Gallery event takes place tonight, July 21st, at 312 Bowery in NYC, from 7 to 10 PM.
