Cat. #00197522: YOKO ONO

Scarce vintage inscribed signature in black felt-tip marker, dated 1986, on a 1978 first day cover honoring a stamp featuring a piano and the caption "Peace unites a nation like harmony in music"-- a notion with which she would assuredly concur.  In very good condition.  The avant-garde Japanese artist, musician and filmmaker was the wife of the Beatles' John Lennon from 1969 through his murder in 1980.  Her autograph is extremely elusive in any format.
