Extra Large Gilbert and George Poster - inscribed and signed by G & G.

I hope i can get some help on this one. I have not been able to find a single other copy of this poster on the net - signed or unsigned. This is a large poster - 24" high by 34.5" across. It's inscribed "For D6ar K6nt' and "X Gilbert and GeorgeX".

i've been a fan of them for a long time. I was invited to this exhibit back in 2008, but i didn't go for some reason. My friends went with them and loved it. They didn't recognize this particular poster though.

Any info appreciated!
