A lot of people fell in love with Rocket Raccoon this summer thanks to the movie Guardians of the Galaxy, so this seems like a great time to pick up some art featuring the movie's angry anthropomorphic star -- and to help out his co-creator Bill Mantlo at the same time.

Mantlo was severely injured when he was hit by a car in 1992, and has needed constant and costly care ever since. The prominence of Rocket Raccoon in Guardians brought welcome attention to Mantlo's condition, and comic artists have stepped up -- in conjunction with Multiversity Comics -- to help fund his care with online auctions of original art featuring Rocket and other Mantlo creations (yes, including ROM Spaceknight). All proceeds will go to the Mantlo family.

Here are some of our favorite pieces from the auctions:

Declan Shalvey
Rebekah Isaacs
Mike Henderson
Joe Hunter
Michael Walsh
Chris Visions

The auctions, featuring all this art and much more, end Sept. 21.
