WonderCon returns to the Anaheim Convention Center the weekend of April 18-20, 2014. On April 1, 2014, DC Comics announced three exclusive comic book variants that will only be available at the convention. Each exclusive comic book will be sold at the Graphitti Designs booth (#301).
Not surprising since this in the 75th anniversary of the introduction of the character, Batman is the featured character on two of the exclusives. With Neil Gaiman's "Sandman Overture" picking up the third.
The Batman exclusives are just part of the celebration that DC Comics has cooking to celebrate the Caped Crusader 75th birthday. First appearing in the comic book "Detective Comics" #27 (March 1939), Batman has become a cultural phenomenon translating to all mediums.
Batman headlines more comics than any other single hero currently published in the United States, and with his extended spin-off family of titles Batman's line of books is bigger than most publishers entire line of books.
