Hi Lynn!

This is the link to the parody: http://yalestewart.bigcartel.com/product/batman-superman-jim-lee-parody-11-x17

I would venture to guess that the shirt maker doesn't have Yale's permission to use his interpretation of his characters. But I can't say for certain, obviously. It wouldn't surprise me if the shirt eventually gets shut down. (I know Yale recently posted about someone using a drawing of his for a purpose he didn't intend on Facebook.)
