This month marks the 20th anniversary of the publication of Mike Mignola's first Hellboy comic. Dark Horse is honoring the occasion by declaring March 22 "Hellboy Day" — and at least one aspect of the festivities will taste as sweet as it sounds.

Renowned chocolatier Richard Ruskell has designed a limited-edition series of Hellboy-themed chocolates that will be available at Los Angeles' official Hellboy Day event (at Meltdown Comics). Afterward, fans can pick 'em up at the Sweet! Hollywood shop or sweetlosangeles.com.

As you can see, the bars come in several varieties — I devoured the "Abe Sapien" sea salt and caramel one — and even have space on the back for Mignola to sign. The bars retail for $9.99 each, and a limited edition of 3-D chocolate figures will also be available.

Comics shops around the world will be celebrating Hellboy Day on Saturday. Dark Horse has a list of events, and you should contact your local retailer to find out about any special discounts or promotions.
