I saw brad pitts autograph twice on autographworld.com and both times it was blue.

I have had several celebs tell me that black sharpies don't look authentic when you scan the pix to post them on eBay, so they feel that signing in black will lessen the demand for that persons auto because fewer people will believe it is authentic. Signing in blue looks more authentic when scanned.

Black is more common to be honest. Viggo Mortenson signs in blue which I thought was weird. But I have found that most big celebs only sign in black.

Yes it is true....I was talking to a grapher last year and he said he had a blue sharpie and Brad pulled out a black one.He doesn't sign in blue.Alot of celebs hate signing in blue.Think it has something to do with Ebaying..Black isn't worth as much.....Could be wrong though.....

Does Brad Pitt ever sign in blue? I think I read that he only uses black. is this true?
