From Omega's Website: Provenance: A family member of the vendor worked for Rediffusion and was present during filming for TV special 'Around The Beatles' on 28th April 1964. As well as taking photographs of the band (twelve 4x6" and one 6.5 x 8.5" black and white prints of those photos included in the lot) they obtained the signatures on this LP on the day. The signed LP came to the vendor on their 21st birthday. Authenticated by Roger Epperson.
Loose as a goose but nicely legible. I bow to higher authorities as to authenticity but being slightly atypical is usually a good sign and the studio photos add even more positive evidence.
