Here's a great starter collection of classic Avalon Ballroom concert posters from the psychedelic sixties in San Francisco. Bands featured include Janis Joplin (Big Brother), The Byrds, Steve Miller, Quicksilver, The Youngbloods, and many many others. Mostly 2nd and 3rd printings but some firsts as well. All are in EX-MT condition. Call for detailed list.
