Props must be given to Pink Floyd for the Animals cover. Even back in those pre-computer days then they could've st ...
Some years back I read a book by one of the guys from Hipgnosis, who did the Floyd's album covers back then.
Yes, the pig was launched above Battersea power station and photographed (and it escaped, causing flights to be diverted, but that is another story).
However, the band ended up agreeing that earlier photos taken without the pig had a much more dramatic sky and clouds.
So the album cover is a cut and paste job, with the pig from one shoot, and the sky from another day.
