Welcome! No, it's not too late to send one. I sent photos but, it would just be a waste of postage to send photos so, don't. send an envelope that would fit a 4x6. I don't know how many UK stamps you need since I don't there, sorry. I heard that it's good to send a few dollars because it is hard the find IRCs there. Send an LOR also saying that you enjoy his work and requesting an autograph. Hope I answered all your questions!

I'm thinking of sending a letter but I have a couple of queries :
1. I live in England and the adress is in America . Should I just slip a couple of dollars inside the envelope?
2. I see he's not signing any one's pictures just sending out pre-signed . Should I not bother to send a picture?
3. How many UK stamps from england to New york?
4. Is it too late to send one?
5. What size envelope should my SASE be or will they provide a envelope for the photo?
Thanks for all your help - (I'm a newbie and I need to find out quickly)
