LeRoy has been in a little bit of financial and legal trouble as of recently. If you are interested in his address it is:
LeRoy Butler
Apt 211,
8500 S Springbrook Blvd
Oak Creek, WI 53154
I know this for a fact, a good friend of mine lived next to him. Good luck, in the past he was notorious for charging quite a bit and that was before his financial legal trouble.
I checked out his website and he's charging $25 for a signed photo that you can order from him, amongst other collectibles. Not sure if he'd sign a card for free looking at that, but it might be worth a shot. Thanks.
