Rock N' Roll High School Soundtrack [Signed]

Very clean promo copy of The Ramones "Rock N' Roll High School" soundtrack from 1979. There is an accompanying flier which was part of the original promo press package, and it is signed by Joey and Johnny Ramone. It has not been authenticated, but the signatures match online examples of their signatures from the 70's. This copy was bought by the current owner at a record store in the late 70's or very early 80's. The vinyl is completely clean. The jacket has very light shelf wear, with a gold promo stamp on back. The flier is very clean, and the signatures are distinct and clear. The rest of the promo packet is not present. "Rock N Roll High School" was released in 1979 and was produced by Roger Corman. It is considered a iconic cult movie of that period and a classic in rock n roll soundtracks.
