Thanks at first!

It helps, yeah. But what kind of stamp do i need...can i use a normal one of "my" country, or do i need one from the us or...sth else?
And how many? :p

hi
when i send to the usa
i include in my envelope i sending to celeb;
my letter
a piece of card to prevent photos from being damaged
a self addressed envelope
and a few $'s(but in your case irc)
photo's (what i want autographing)
hope that helps

I read the threads above, but i'm not sure that i understood everything well enough.

If i want to send a letter to the US, from Europe..i have to buy an envelope, put in my letter, photo/s, and IRC's?
And put an IRC on the envelope too?
And write my and the celebs address on the envelope plus the sentence: "PLease do not bend."?
