Philip Weis Auctions recently sold a copy of the first Detective Comics for $25,000.00. Throw in a little Batman a few issues later and you get over a million, but $25k is nothing to sneeze at. Detective Comics #1 (March 1937), has cover art by Vin Sullivan depicting the Fu Manchu-style Oriental villain Ching Lung.
Here’s the auction description:
Rare. Rare. Rare. Unrestored. Overall looks fine or better. These books were bought off the newsstand by noted illustrator and cartoonist Eldon Dedini. Mr. Dedini marked each book with his inventory number and signature on the cover. In most cases these do not detract from the vibrant colors and crispness of most of these volumes. The overall page quality on these books is remarkable.
