This set of two posters and the original artwork were created by design duo Michael English and Nigel Waymouth, known as Hapshash and the Coloured Coat, here credited by their old name, Jacob and the Coloured Coat. In the late 1960s they created psychedelic posters for many of the English bands of the time, and decorated and advertised Nigel Waymouth's King's Road boutique, Granny Takes a Trip. They also designed for concerts held at the UFO club and Saville Theatre, and for underground magazine Oz. Their influences came from the decorative and eroticised designs of Art Nouveau, combined with the melting rainbow colours of LSD visions and pop art inspirations from the post-war media; traces of Disney, horror movie monsters and comic book characters and can often be seen hiding amongst the images.
