One of the best parts of any comic convention is going through bins and art folders, looking for that back issue you've been missing for years, or a piece of art to add to your collection. Even if you're only "window shopping," it's usually a good time.
But that wasn't the case for Al Plastino at this year's New York Comic Con. The renowned Silver Age artist, writer and editor, best known for his contributions to Superman in the 1950s, discovered that his art from the commemorative edition of Superman's Mission For President Kennedy -- printed soon after the president's assassination -- was in the possession of an exhibitor at the show, and was about to be auctioned off. The only problem? For the last 50 years, Plastino believed the art to be in the John F. Kennedy Memorial Library, where he was told it had been donated.
