I sent Andrew an LOR, a photo of him and Steven, (zombie photo) and an IRC on 9 February 2012, to the addy in the database.
Today, on 26 March 2012, I recieved my previously signed Steven Yeun photo back signed, as long as another photo from him, which I believe is pre-signed (different markers used), and a small note.
All the items+envelope:

By the way, can anyone tell me what Andrew wrote on the note? Thanks!
