My name is Gerry Hart. I've been dealing with all sorts of ephemera for twenty years. I base my comic book prices on values from comicbookrealm.com or comicpriceguide.com(affiliated with CGC). I base my other ephemera stock(magazines, books, trading cards, and toys) by different price guide websites. I am willing to cater to your needs. Check the Faqs and Terms for any further questions.
