Original 1967 Moby Grape / Baltimore Steam Packet Psychedelic Concert Poster – Lichtenwalner – Gate 6 Sausalito – Oct. 7, 1967 Measures 16″ x 22″ Original vintage 1967 psychedelic dance concert poster designed by noted psychedelic artist Lichtenwalner featuring Moby Grape and Baltimore Steam Packet at Gate 6 / The Ark in Sausalito during the height of the Summer of Love era. Lichtenwalner’s work is highly recognizable for its flowing hand-drawn psychedelic typography, intense fluorescent color combinations, surreal imagery, and strong Art Nouveau influence. His posters were part of the explosive late-1960s San Francisco Bay Area counterculture art movement that helped define the visual identity of psychedelic rock music alongside the Fillmore and Avalon Ballroom poster scene. This example features vivid day-glo fluorescent inks in purple, lime green, metallic gold, and silver with dramatic blacklight-reactive visual impact. The central surreal figure and distorted lettering are classic hallmarks of authentic 1967 psychedelic poster design. Poster text includes: Dance Concert Baltimore Steam Packet Moby Grape His Other Possibilities Gate 6 Sausalito Lights by Funny Co. Colors remain exceptionally vibrant and display beautifully under both normal and blacklight conditions. Please review all photographs carefully for exact condition and measurements. An outstanding and increasingly scarce example of original San Francisco psychedelic poster art from one of the defining visual movements of the 1960s counterculture era.
