Yeah, they are definitely authentic.
He signed it as Dan said, because he is the reason while Karl is famous. ;)

[color=#0000FF]They're authentic! Ricky is associated with that photo he signed though, the guy is the main star from "Idiot Abroad" which is Ricky's show. 8) [/color]

I'm no expert on him, but the fact that that he signed a picture of someone else with no questions asked causes me to question authenticity..

I loved this guy in everything so I thought it was time to write to him.
I sent a LOR, SASE and 3 Photos.
One photo was of Karl Pilkington, not sure how it got in his envelope but he still signed it!
Not personalized, but really happy!

This as before I heard of Derek, so I might send another off to him as that role.
