According to the CAPS website:
On Thursday, March 6, 2014, Southern California's CAPS, the Comic Art Professional Society, will launch an ongoing series of eBay auctions of original comic art. Its goal is to raise funds for medical care for Sharon Sakai, the wife of respected cartoonist and longtime CAPS member Stan Sakai, creator of the samurai rabbit USAGI YOJIMBO. Sharon has been battling a debilitating brain tumor for some time; after an extended hospital stay and convalescence, she is currently at home, but her condition requires 24-hour care and medicine that costs more than the Sakai's insurance covers. 100% of the proceeds of these auctions will go directly to Stan and Sharon Sakai to help pay their ongoing medical expenses.
I'm proud to be a part of the auction, and support one of the most important and enduring independent creators in the business, Stan Sakai!
The picture should go up for auction in a couple of weeks. I'll be sure to let you know when, as soon as I do.
