Uncommon original invitation from Harvest Records, 6 x 4.25, for “an exclusive playback of the new Pink Floyd album ‘Animals,’” to be held at the Battersea Power Station in London, England, on January 19, 1977, just two days before the album was released. The front features ‘flying pig’ imagery similar to the album’s iconic cover (which pictures Battersea Power Station), and the back lists information text, a map, and the invitee’s name in red ballpoint. In very good to fine condition, with scattered creasing, and a heavier diagonal crease to the lower right corner. Accompanied by a certificate of authenticity from Tracks.
