These are concert programs I purchased as souvenirs. I have four of them, from 1983, 1984, 1985, and 1988. Some have slight stains (the insides are clean). The largest one, from 1988, has a slightly bent corner on the back, and the band-like obi that was on the front and back is missing. Please be aware of this. I would appreciate it if someone who understands this would purchase them. Thank you for looking.
