“Grimm,” the popular TV show from NBC, held an auction to help the OHSU Doernbecher Children’s Hospital earlier this year. The Grimm Gala, a fundraising event hosted by the show’s cast and crew earlier this year, helped to establish The Grimmster Endowment.

Two of the items that were part of the fundraiser were signed pairs of Air Jordan Xs, both of which had Michael Jordan and Tinker Hatfield’s autographs.

MJ and Nike’s top designer put their signatures on an all black men’s pair and an all-white women’s pair. The women’s pair included plush fur on the lining. See the photos above.

Here’s more from Nike:

This year’s gala grew the endowment by over $386,000, with additional funding on the horizon. The Doernbecher Foundation will auction four pairs of each “Grimm” Jordan X colorway through eBay for Charity with all proceeds going towards the Grimmster Endowment.
