"Hapshash and the Coloured Coat, the 1960s design duo comprised of Michael English and Nigel Waymouth. The two artists, together with associate Martin Sharp, are indelibly associated with the London psychedelic scene of the late Sixties. Whereas Sharp’s posters were often loose and dramatically bold explosions of shape and colour, the Hapshash posters were more carefully controlled in their curating of disparate elements borrowed from Art Nouveau—especially Mucha and Beardsely—comic strips, Op Art, Pop art and fantasy illustration. Their work perfectly complemented the very distinctive atmosphere of the capital’s psychedelic scene which, for a couple of hectic years, saw an explosion of new bands (or old bands in new guises) fervently engaged in a lysergic exploration of Victoriana, childhood memories and frequent silliness. English and Waymouth’s graphics captured the London mood." Quoted from http://www.johncoulthart.com/feuilleton/2009/10/03/michael-english-1941–2009/
