If you want to ask for a signed photo, because in It is almost difficult to buy photos of foreign celebrities in Taiwan, so when you send it, just write "I want your signed photo, I have attached a stamped return envelope" and basically the other party will give it to you.

You can go to a stamp agency to buy US stamps....it depends on which country you want to send to, go to the post office. Just check the postage...
