In the Q & Mojo Classic Special Edition Pink Floyd & The Story of Prog Rock, the album came #34 in its list of "40 Cosmic Rock Albums".

[2] The cover of the original vinyl release was designed by Laurie Lewis.

The front and back outer cover is a panoramic photograph of Reykjavík, with the sky on the right merged with a transparency of a 15th-16th century fresco in Orvieto Cathedral by Luca Signorelli, "The Damned".

The inside gatefold is a collage that includes photographs of the personnel and guests involved in the music, the cast of the TV show Bonanza, together with a cropped photograph by Jacques Henri Lartigue of a man throwing a dog.

[3] The 1987 CD re-release of the album added two bonus tracks, the A- and B-sides of a 1974 single, previously available on the 1980 compilation Afters: The 2009 Esoteric Recordings reissue (ECLEC2139) also included the above, along with a further bonus track: Taken from the Virgin Records Sampler (VD 2502) from January 1975.
