On November 18, 2021 a large collection of prints, contact prints, negatives and ephemera from the estate of Anthony Clifford Burls (AKA Cain of London) was sold by Dominic Winter Auctioneers for £6,000.

Not so well known on this side of the Atlantic, Cain photographed shirtless fairground workers, footballers and guys in leather, often on motorcycles. Most of the photos were taken in the late 1960s and early 70s.
