Psychic Pedestrians On a Spiral Horizon (Barycenter) (1971)

Truly an absolute masterpiece by one of the seminal underground artists and the founder of the "lowbrow art" movement, this densely intricate (and huge) psychedelic tour-de-force has to be seen to be believed. Published as the wraparound cover to the classic fanzine Promethean Enterprises #5 in 1974, and in scores of portfolios, publications, postcards, and posters since then.
The inverted horizon evokes classic science fiction tales of "worlds within worlds," even calling to mind Larry Niven's Ringworld series. This dizzying piece is packed with intricate detail and hidden surprises throughout. The central golden god-like being brings to mind the cosmic horror of Lovecraft, and the bearded gent's grin is unsettling to say the least! An amazing trait of this work is that it can be hung with any side up to refresh the image for the viewer. It's certainly rare when an example by a hugely important - and influential - artist comes to market that immediately registers in our minds as the indisputable "best of the best" - and this is it!
