Old 1984 Signed Cardboard Cylinder

I found this cylinder in the back of a cupboard and some of the signatures are fading. The poster is long gone but there are a number of sigs and a few I checked on line are either authentic or very good forgeries. I can’t even remember how I got it but it’s from 1984.
If it’s of any use to anyone, and you’re willing to pay postage, send me a note. Otherwise it’s back to the back of the cupboard until the coonara needs kindling.
