The note sees John accuse the EMI record label of blocking distribution on his 1968 experimental album ‘Unfinished Music No. 1: Two Virgins’, because he appears nude on its cover with Yoko Ono, who became his wife in 1969.
In the letter, John angrily writes: “EMI (who have the real control) wrote warning letters to all their puppets around the world telling them not to handle it in any way.”
John’s ambition was to ensure that he would avoid a repeat of his experiences with EMI, which also distributed The Beatles’ Apple Records releases.

Of the letter, Moments in Time dealer Gary Zimet told the New York Post newspaper’s Page Six column: “This is Lennon’s handwritten draft letter … The letter is angrily written, and this album was the very first non-Beatles album that Lennon made.”
And ultimately, ‘Unfinished Music No. 1: Two Virgins’ – which was released with brown paper-bag packaging – was distributed by another record label.
