Hello, I want an autograph from burn gorman. I have a working address, and want to have him sign an index card. He lives in the UK. I live in NY. So I know I need to go to the post office to send it, but with the SASE do I need to get some uk stamps to put on the SASE to send back from the UK, do i need some international reply coupons, or can i just use US stamps? And where can i get the stamps and coupons, how much will they cost, and how many do i need to ship back? Thanks.
