I got the exact same one execpt it said " Happy Birthday" on top. It is defianatly authentic because my strokes are slightly more slanted and neater. Congrats! I got mine when emailed a lady called Jane, I think, from his foundation.

I emailed Deron's charity on 3/31/14 and received a 4x6 today on 5/1/14. Awesome guy! Judging from the pen stroke, this is definitely not PP or AP. Signed in silver, very happy, thank you Deron!
