Pink Floyd, Meddle (Band), Inner Gatefold, 1971

1971's Meddle represented a shift from Pink Floyd's early psychedelic roots to a more progressive rock sound. For the gatefold of the album, four superimposed black-and-white photographs were used. This was the last time that the four members of Pink Floyd appeared on an album sleeve, until 1987's A Momentary Lapse of Reason.

Release Notes:
In 2008, Storm and SFAE celebrated Pink Floyd's 40th anniversary with an exhibition of signed photographs of images that he had created for the band over the years both as a founding member of the design collective Hipgnosis, and as an independent designer with StormStudios. These photographs were produced as signed, open editions and were only briefly available for sale as they were intended only for the anniversary celebration. Very few of any of these images were produced.
