I sent Chevy Chase a LOR, SASE, & 4 pictures to the address in the database on 1/05/2013:
Chevy Chase
P.O. Box 257
Bedford, NY 10506
(First photo)

(Second photo)

(First & second photo combined)

(Third & forth photo).

Today (4/15/2013), I received my 4 photos signed in my sase. However, I suspect they are auto-penned. If you look closely at the signatures, each signature looks similar to the others. Plus, the signatures look shaky which implies the use of an auto-pen. Feel free to give your opinion. Thanks!
