More proof that Australians are crazy. From the State Library of New South Wales:
The photographs illustrate drunkenness in five stages, played by a male subject in a studio. Possibly commissioned by a local temperance group for educative purposes, the photographs may also have been used by an engraver for illustrations. The penultimate frame of the drunk in a wheelbarrow resembles S.T. Gill's watercolour 'Ease without Opulence', 1863 (PXC 284/30). The printed studio mark on reverse reads "Photographic Artist. C. Pickering, 612 George Street, near Wilshire's Buildings, Sydney"
It's also possible that these images were commissioned in response or relation to the Drunkard's Punishment Bill, introduced by New South Wales Premier James Martin in 1866.
Now that all that history's out of the way...I don't know, I think it's pretty accurate.
