I sent Deron 2 requests this year. This is 2 of 2.
Address: c/o his Salt Lake, Utah address
Deron Williams - current NBA superstar of New Jersey / Brooklyn Nets. 3x NBA All-Star, 2× All-NBA Second Team (2008, 2010), NBA All-Rookie First Team (2006), Skills Challenge Champion (2008) among others accomplishments.
Signed four trading cards and one 4"x6" custom photo.
For questions on the authenticity of the autograph, we can compare it with his 09-10 Crown Royale Majectic Autograph card...especially the last "L". And YES, Deron has an active Salt Lake, Utah address. Therefore, I believe the autographs are personally signed by Deron.
