Chip Zdarsky's Jaxxon variant cover for Marvel's Star Wars: Vader Down #1 is so rare -- retailers had to order 4,999 copies to get just one variant -- that it's sold on eBay for upward for $4,000. But now you have a chance to get your own copy for a little less, and help a good cause in the process.

Zdarsky signed his sole copy of the variant and donated it for a charity auction to help raise money to bring a Syrian refugee family to Toronto (the cover is being graded by Certified Guaranty Company). After just four bids, the price is already up to $1,500 Canadian ($1,122 U.S.).

In addition, Zdarsky has donated a signed copy of the Sex Criminals, Vol. 1, hardcover, which has hit $75 (abut $56 U.S.). The auction ends Sunday.
