I try to always save my playbills.
Unfortunately, when I first started seeing shows I was a young teenager (like, 13), and I had a tendency to cut everything up, and put it on my wall. For example, I cut the cover off my nice, autographed broadway CATS playbill, and hung it up. I also cut the pictures out of my POTO programm.
I'm over that now though. I usually grab extra playbills when I go see plays, to give to my friends. My own playbills are scattered everywhere, but I never throw them out.
