14x20" stiff paper poster for May 12-13, 1967 concerts at Avalon Ballroom that featured The Doors and The Sparrow. FD-61 w/art by Victor Moscoso. Known as "Butterfly Lady" and the central image is a picture of a woman w/two pairs of wings done in a manner so that if viewed alternately through a red and blue lens, it would appear as if the wings were moving and the woman was dancing. This is a second printing done shortly after the initial printing. N. Mint.
