Liverpool Birthplace Of The Beatles Rare Postcard

ts181 This is an undated but would appear circa very early 1980s postcard of The Beatles (further validated by the phone number on reverse not being prefixed by 01) - it appears part of a collection of postcards from The Beatles Cavern Tours of the era and shows the Fab 4 and how Liverpool Was The Birthplace Of The Beatles with reverse detailing about the Beatles convention held annually - it is unused bar just one small corner fraying place otherwise mint condition and surely very limited as I cant find another listed anywhere.
