I'd say these 2 pics are the closest legit pics out of his clothed base covered dick pics.
His hand and juice glass and he states it's hard. Def not 10" but with the juice glass? You at the least get a close base mark and not the optical illusion of it being longer by the way he has it exposed.
Another good pic showing a more realistic size. Still not 10" and I'm sure he's going to say its not hard. Just because he has his foreskin pulled over the head.
Few of the pics are allover Google but the tumblr he frequents has more of the same base covered illusive angles and camera trickery.
