17" by 12" poster of Jimi Hendrix. Explosion. By Martin Sharp-Big-O Famous. During the first half of 1968, Australian artist Martin Sharp (1942-2013) produced this stunning painting in acrylic on mylar of Jimi Hendrix. A variant watercolor version was shortly thereafter transformed into a page for London’s underground OZ magazine and a poster entitled Explosion, which was offered for sale by the Big O Poster company. Sharp's Explosion is one of the iconic posters of the late Sixties - capturing a moment in time when the excitement and energy of Jimi Hendrix was combined with the psychedelic art of the time to produce a truly explosive work.
