Anyone know the address of Zedd? He produced the songs Clarity and Stay the Night.

All I got today was this index card. The return address said "Los Angeles, CA 900." I think it's from Tom Hanks, but I'm not sure. Any ideas?

After some searching, I think that this is Slash from Guns N' Roses.

I received this in the mail today. It was just a plain index card with this signature. All it said was that it was from "Santa Clarita, CA 913." Underneath it, it said "15 JUN 2013 PM6L." I can't make head or tail out of who it could be. Help! http://s1148.photobucket.com/user/aj...

Here's all mine:
