As I get older the want list gets smaller, partly because I have more, but also because I get more focused and realise owning a thousand posters is more than enough in fact it's stupid unless I manage to inherit a mansion (unlike some who enjoy them being packed away)
Although I do have a lot that I wouldn't display ever, so I do enjoy them packed away to a degree.
But anything that isn't part of a specific collection that I try and be completist about, they are in my mind at least to be displayed at some point in time.
