High Voltage album signed on the back cover in red and blue ballpoint by Angus and Malcolm Young, Cliff Williams, and Bon Scott, the latter two signing first name only, and each member adding “AC/DC.” In very good condition, with some creasing and staining, and the Williams and Scott signatures a shade or two light. The record is included. Accompanied by a full letter of authenticity from REAL, and a letter of provenance from the nephew of the original recipient, in part: “He acquired the signatures whilst working at a local hotel in Newcastle-upon-Tyne. He had heard a rumour that an established band would be checking in and as he knew AC/DC would be playing at a club in Newcastle called ‘The Mayfair,’ he put 2 & 2 together and brought in his album collection for them to sign. This was approximately during 1976–1978.”
