Dave Henderson has always been one of my favorite players and is one of the best TTM (through the mail) signers on the planet! His son suffers from a rare genetic disorder, and he humbly asks that you donate 3-5 dollars for his autograph to the ANGELMAN SYNDROME FOUNDATION. If you would like to write Dave for an autograph his address is: Dave Henderson, 2213 Halleck Ave SW, Seattle, Wa. 98116. Thanks Dave for being classy and always looking out for your fans! Oh, and don’t forget to include a self addressed stamped envelope.
