1.The Sunbaker, a 1937 photograph by Max Dupain, is one of the most well-known Australian images of all time.
2.But the image wasn't actually printed until 1975, when it was featured in a retrospective exhibition of the work of Dupain (pictured below).
3.This is because the negative for Dupain's preferred version of the image was actually lost. Today, only one known print of this version exists - shown below, from a collection at the State Library of NSW.
4.The collection also features this photo, which showcases an entirely different angle of the image.
5.The man in the photographs is Harold Salvage, a British builder and friend of Dupain's.
6.The shots were taken on a camping trip to Culburra Beach on the south coast of NSW.
7.A large group of friends went on the trip with Dupain and Salvage.
8.One of those friends was builder Chris Vandyke, who owned the collection of these images that is now at the State Library of NSW.
9.Also on the trip was fellow photographer Olive Cotton.
10.She took many photographs on the trip herself, including this shot of Dupain and Vandyke.
