I am aware that Emilia Clarke sends back pre prints in the post. SoI'm wondering what should I send in the envelope in such case. Will I bother sending a photo? Or will a simple letter or request suffice? I'd imagine I'd still have to send a SAE with IRC's though.

Also, what other celebrities do pre-printed autographs? If I'm likely to get one, no harm in sending one out.

Thanks in advance.
