I have never sent a fan letter before so I need some help with postage.
I'd like to send a letter from Canada to the UK, with hopes I will get an autograph back. What stamps do I need to put on the two envelopes? Sorry, This is all quite confusing. Thank you in advance, however!

to = Canadian stamps
SASE back to = UK stamps or IRC's
