Welcome to The Peculiar Manicule’s shrine to the unsung heroes behind Hallmark and American Greetings’ distinctive style of pop-infused psychedelia. In the late 1960s and early ’70s, these prolific — and often overlooked — studio artists helped usher psychedelic-style graphics into the mainstream. Blending counterculture imagery, pop art flair, wild typography, and irreverent humor, they created a body of work that was both crowd-pleasing and quietly revolutionary. Behind all the sugar-coated surfaces lies some of the boldest, most inventive design of the era — made by artists who rarely get the credit they deserve.
