Iron Butterfly AUM Cal Expo Sacramento, Dec 20, 1967. This is a very rare original handbill for this cancelled Cal Expo Show. Condition: VG -- there are 8 pinholes top and bottom center plus two thumbtack holes. There is also a bit of printer's ink on the bottom portion but I would surmise that was on many or even all of these. There are a few soft bends but this bill has been stored in a sleeve flat for many, many years and looks great. Color is bold, no fading.
