Check out the hellcat design group website. They handle a lot of Eric's merch. I took the pic off that website to my tatoo guy.
What about the one on this page, on the lower left hand corner? Or on the CD? Do you have a GREAT tattoo artist? I bet he/she could do one from the one on this page.
You could do a screen shot, crop it out and bring it to him/her? I don't know, just a couple thoughts. Good luck and be sure to post pictures when you get it done!
