If you are wondering how to send fanmail, here are some suggestions on what you should include:
1) Letter—Michael seems to be wonderful at reading letters and personalizing photos
2) Photo—It could be any size, just include a SASE big enough for your photo. You can also include a piece of cardboard with your photos to keep it from bending or just write DO NOT BEND on the envelope.
3) SASE (Self-Adressed, Stamped Envelope)—You can get a reply without sending one, however, it is always nice to include it, and, it will increase your chances of getting a respose. It would also be wise to write DO NOT BEND on this envelope, as well so nothing happens to your photos (even if you don't send him one, he may send you one from his promo photos) on their way back to you.
4) IRC's (International reply coupon)—Use only if you live outside of the United State. Because you are sending it to Hawaii, USA, the number of IRCs neeeded is dependent on the size of the photo you are sending. For example, f you are sending something like an 8 x 10, then 2 IRCs should work.
That's about it. Generally there seems to be about 1-2 months wait to get the photos back signed. Good luck!!
