Anyone know the album/artist which on the sleeve has a photograph of two women tying their hair on one head?

Question

Basically I'm thinking it's a classical album, most likely from the 70's, it's a colour photograph, one woman is sitting and tying her hair up, from behind her is another female torso helping her, but they have the same head, the second woman is leaning forward so her neck merges into the main woman's head, it's a really convincing photograph, for a while I have thought it was a prog-rock album form the 70's, now I'm not so sure.
