This is a tribute to legendary blues singer, Billie Holiday. Both vessels were identically constructed and then turned differently. Of interest to fellow woodturners, the vessel on the right was never sanded, only shear-scraped. Lady Sings the Blues was released in 1956. A few lyrics:
Lady sings the blues I'm tellin' you, she's got 'em bad But now the world will know She's never gonna sing them no more.
