Robert Lockhart has nearly a hundred Discogs entries for his design work and could turn his hand to many different styles. Above is his interior gatefold for Gene Harris of the Three Sounds LP from 1971 which displays a fine grasp of the airbrush as well as collage. Below, his Bloodrock sleeve mixes S. Clay Wilson with Milton Glaser and comes up with something in the middle.

Above’s Bob Seger LP back cover displays more affection for the Milton Glaser style that was so popular back in the early 70s and below Lockhart whips up a fine collage for the front and back of Quintet’s ‘Future Tense’ LP, then channeling Michael English/Richard Hamilton for the cover of Steely Dan’s ‘Can’t Buy A Thrill’.

I’ve shown this before; Ravi Shankar goes psychedelic (for the cover at least) and below that an oddity of the Pablo Light Show providing visuals for a ‘Heavy Organ’ recital of Bach in San Francisco with cover illustrations very reminiscent of Victor Moscoso.
