Nah dont do that...You'd never see your pen and paper back...he'd just scam you out of them. Throwing some line like hey he needs 40 cents for a postage stamp....and then something about being too busy...and then you'll ask him later....and he'll say he needs like 38 cents...for a stamp....cuz he's got a few pennies saved....then he'd drop off the face of the earth....then he'd say hey I sent it to you....then make up some excuse that you lost the autograph or it got damaged or lost in the mail.

Just get the guys from japworks to pose for a picture in front of the celica and autogragh that instead....
Cuz it'll look trick!
