If you need an incentive to help a two-year-old boy with his leukemia treatment beyond basic human decency, how about an original page from one of the best Batman stories of the past decade?

An eBay seller is auctioning off the above page from Detective Comics #871, the first part of the acclaimed "The Black Mirror" storyline by Scott Snyder and Jock, to help a little boy named Nathaniel, who has acute lymphoblastic leukemia. Jock himself donated the art for the auction.

From the eBay description:

His prognosis is good but he has a long, not very nice, course of treatment ahead of him over the next few years which will involve the family travelling regularly to hospital.

And in regards to the condition of the art:

Never Framed/Displayed. Stored safely in my flatfile since I picked it up the other day from Jock directly.

This piece will be shipped very securely.  I will wrap it in tissue paper then kraft before sandwiching between pieces of rigid foam board.  This will then be wrapped in bubble wrap before being put in a box.

As of Wednesday morning, the highest bid on the art was 267 pounds, or about $430. The auction ends Sunday.

Snyder and Jock are teaming up again for a new Image Comics series, Wytches, which starts up in October.
