The one other thing with linen backing is Value!! most of the predominant dealers/collectors say unrestored, unbacked posters are the way to go, as this is where the bigger money will be...
Well in my experience it seems, linen backed posters always go for that little bit more. I know that no one can predict the future, but I say this will always be the case. It has been for the past several years, and I don't see a change in buying habits!
Maybe some of the bigger sellers could give a bit of insight. Bruce, Rich, Phil, Terry, and any of the others. I'm great at buying, not so good with selling. So it would be good to hear how things are from that side of the fence.
