Norman Lindsay was a prolific Australian author and artist who worked in many media. He's known today mainly for his delightfully erotic line drawings featuring full-figured female nudes. Michael Powell's last film was an adaptation of Lindsay's novel The Age Of Consent, and a film about Lindsay's life, Sirens, was released in 1994.
The image above, from 1938, introduces a frankly erotic element into the foursquare narrative style of N. C. Wyeth's illustrations — a slightly startling combination.
Age of Consent was Helen Mirren's first major movie role.
Quite a good film, too.
