Nice! I want to send him soon!

Sent a LOR, SASE, and two autograph cards to John Williams sometime within the last two years. Received my cards unsigned but received a pre-signed index card on March 15, 2019. Super excited to have this legendary signature! Sent to the address in the database http://surfmypictures.com/image/448826...

Krist normally is a pretty good signer through the following address. He has signed for me several times. Try
