You're in luck! It was not signed. It was after the weigh-ins and some people asked for him to take photos. He very politely said he couldn't because his "crew" (his word) was starving and they had to get to dinner. Then he turned to some other guy and said, "Make sure they all get pictures." Then the other guy gave everyone there 8X10 unsigned glossies of Kimbo. Later I took some pictures with Gina Carano. She was a doll. She would pose for a regular picture and then say "Now let's do a funny one!" and she'd stick her tongue out or whatever. For my "funny one" I held the Kimbo Picture up in front of my face.
Side note: About two minutes after the guy handed out the pictures and Kimbo and his crew left, Bas comes running out of the building shouting, "They're leaving without me!" and runs after them.
