Yes, He had permission. I asked about that and he has a deal with many of those in the Sci_Fi industry. He does all of the MegaCons, ComiCons etc. In some desgins, he's doing more of a parody such as in Scar Face. Others are famous monster shows. Many of those (like this one for a tattoo convention) are sold at conventions and the tattoo go-ers seem to be much of the same customers as with Sci-Fi conventions. From what I remember, he pay's royalties for every tee sold and any other products.
