I'm reading a book a book by Alice Denham, 'Sleeping With Bad Boys', because she has a chapter on William Gaddis, my fave writer.
In the book, she mentions that she posed for many jazz LPs, and shows her posting for an album called 'Four Lessons in Jazz',featuring Art Blakey, The Australian Jazz Quartet, Johnny Richards and Charles Mingus. She's shown on the cover in front of a blackboard, smiling and letting it all hang out.
I've always wondered who these beautiful women were in real life, and she had quite a story:
