John Lennon's Lost Guitar

In 1962, a special Gibson guitar of which only two were made, was flown from the USA to England for Lennon and George Harrison. He used it for a year before swapping it with Harrison in 1963, after which it vanished. Forty years later, it was discovered that someone brought it into a music shop from where its current owner purchased the guitar. Its current owner discovered that it belonged to Lennon after reading a magazine article, after which that guitar sold for $2.4 million.
