I sent an LOR, SASE, and 8x10 pic to Eric Stonestreet (Thruline Entertainment, Inc. 9250 Wilshire Blvd, Ground Floor Beverly Hills, CA 90212-3343) on 8/25/15 and received back on 9/17/15. He didn't sign my picture, but sent it back with an 8x10 signed from him (does not look like a PP).
I am not posting the envelope since it was my name/address for both recipient and return (SASE).
