This spring, Heritage Auction Galleries in Dallas, Texas is selling a comic book collection with some of the world’s most valuable comic books included. The collection built by Denver media executive Rich Kylberg has been valued at well over $500,000, and will be sold by Heritage on May 22, 2008 with no reserves.

Kylberg’s collection has been described as the best complete collection of the world’s top comics. It includes the first appearance of Superman in 1938, and the first appearance of Batman from 1939, along with first appearances by Spider-Man and the Fantastic Four.  “Mr. Kylberg’s outstanding collection also includes the first comic book appearances of Captain America, Green Lantern, and the Flash, and he’s got nice copies of most of the key Silver Age comics as well, most notably the 1960s debuts of Spider-Man and the Hulk, and other gems like a Near Mint Plus copy of Richie Rich #1,” Heritage Vice President Ed Jaster described of the collection.

Many other major characters are featured, such as Mickey Mouse, Wonder Woman, X-Men, Aquaman, the Punisher, and more. “At some point, I thought: why don’t I buy really beautiful copies of every key comic book?” Mr. Kylberg explained. “It was very challenging and frankly very expensive, but at no time was it about investment, or anything other than compiling a collection of absolute key comics.”
