Variant covers are no rarity in the current comic book marketplace, but that doesn't mean publishers aren't trying to continue to push the envelope. Marvel announced a "shrinking variant" for "Ant-Man" #1 last month, and today revealed artist Ed McGuinness's actual image for the cover -- along with more details on exactly what a "shrinking variant" is.

Each and every cover will be individually numbered and depict lead character Scott Lang at a different size -- from big to tiny -- leading to Marvel's promise that "no two variants are alike." The publisher advises to retailers that it will "only be producing as many as are ordered," with more specific ordering details to come.

"This is completely unlike any cover we've ever attempted," Marvel SVP Sales & Marketing David Gabriel said in the official press release. "We've even had to utilize new technologies to make it happen."

"Ant-Man" is slated to debut in January, from the creative team of writer Nick Spencer and artist Ramon Rosanas. McGuinness's "shrinking variant" follows below.
