I want to send something to Jim Thome and I didn't know if he would sign my Phillies poster even if he doesn't play for them should I include a index card encase?

Hi, they used my SASE SO NO ENVELOPE

I buy the envelopes with the peel off back for them to use seems to make them happy (I HOPE)

I got my Tom Seaver card back today and When I opened it My card was there but not signed But also a little card shaped like a baseball and had a Marketing agent on it so it wasn't a success I used address in database.
