Found today in Skoob Books at the Brunswick Centre (sorry a little blurred).
It was designed by George Mayhew in 1964. He was one of my favourite designers from the early 1960s. He created many beautiful silk screened posters for the Paris Pullman cinema and the Royal Shakespeare Company. Along with Derek Birdsall, Peter Wildbur and George Daulby formed BDMW Associates a short lived super group of the sixties.
