Rare Tusk Poster

[pierrefun]

I used to work for Fleetwood Mac. Attached is a poster made for the TUSK album that incorporates some elements created by the artist Peter Beard for the interior album cover. I understand the band members each got one poster and then the plates were destroyed because Warner Records didn't like it. I got a copy from the printer. I have never seen this anywhere else and cannot find it on the internet. I am interested in any further information. does anyone know its value and where might be a good place to sell it?
