to address something Mel said, indicating how older collectors don't care about misalignments and keep our stuff in boxes
well #1 it is impossible for most any collector - even small ones - to exhibit all their stuff. It's impossible for someone like myself to exhibit what would take a large museum to hold.
second, Mel, some people only collect to have cool things or like cool things etc.
Others, like myself, are historians. We collect the paper for different reasons. My collection of gambling themed posters - you realize that paper from before 1930 is very rare in almost all cases, so you take what you can get until the day comes (if ever) that you see it again.
I'm doing more photography of my collection shortly, I'll post some stuff that is nearly disintegrated. When I do my book, you can believe some pictured material will be in this condition
