Anthony, part of your statement - the Monet to Dracula comment - actually doesn't quite work today.
Look to comics art collecting. The large majority of comic art collectors actually think that comic artists are better than easel artists and I have heard many exclaim that Todd McFarlane is better than Van Gogh. I'm sure there are many people who would prefer a Dracula poster to a Monet, though it is wrong headed
on million dollar price sales, except in a retail environment, you need at least 2 to Tango
That's kinda what I was getting at with the 'age' factor.More younger people have wealth,as we can see in this hobby and others as of late.They're buying,but buying more within their age.They're definitely going to favor Dracula or McFarlane over Monet.Artwork of a scary monster, or flowers....
They loved comics when they were kids,Star Wars,Cars,but there's not many that loved 1930's Universal films/monsters.So,that means these new collectors with cash will have to discover past film stars,get hooked on them,or get hooked on posters.The odds of that happening to many wealthy people is low.
I believe some of these new millionaires have joined the hobby,but I'm not sure Universal is why they're here.Also,there's not alot of collectors in the hobby that like everything.So,if they come in likeing Star Wars will they spread to other genre's? Universal? Seems unlikely.There are very few posters that are ever gonna hit a million.It will happen eventually,but I'm not sure they'll be a bunch of new collectors making it happen.Being a poster collector takes special person...not everyone has that gift.
Bottom line,to Chris' point,there are many people who would prefer Dracula to Monet,but there's many more in the art world and high society alone that would have us shot for even thinking such a thing.
