Martin Sharp, ‘Exploding Hendrix,’ 1968.
 
The late great counter cultural figure, poet and publisher Felix Dennis collected an incredible array of psychedelic advertising posters during his lifetime, from the 1960s and 1970s.

Dennis (1947-2014) started off as co-editor of Oz magazine and was responsible for the legendary issue #28 of the magazine better known as “Schoolkids Oz” which led to the magazine’s famous obscenity trial in 1971. After his experience with Oz, Dennis went onto become a very rich and successful publisher of various magazines like Maxim, Fortean Times, Bizarre and Viz Comics.

Apart from publishing, Dennis also had a passion for collecting—the scale of which was only apparent after his death in 2014. Dennis collected original American underground comic book artwork, woodcuts by Eric Gill, and some 23,000 books—including rare editions by Sir Arthur Conan Doyle and Robert Louis Stevenson. However, books and comics were for reading and enjoying—his real passion was collecting original psychedelic posters.

Dennis was very particular in which posters he collected—he was more interested in following individual artists than “obsessively ticking things off a list.” He was a fan of original Oz artist Martin Sharp, and followed other graphic artists such as Hapshash & the Coloured Coat, Victor Moscoso and Ivan Tyrrell.

The following selection is but a small selection from the Felix Dennis Collection—but gives a rather dazzling (if retina burning) flavor of 1960’s psychedelic art in all its glory.
