How I Authenticate Original Posters
One of the things I love most about collecting original posters is the research. When provenance isn’t documented, the work starts there — studying the object itself and cross-checking historical records until the evidence either aligns or it doesn’t. Authenticity isn’t about one detail; it’s about whether everything points in the same direction.
That’s the case with these Walter Jardine Tooheys posters, which show strong evidence of being period-original commercial lithographs from the 1930s–1950s.
The framer:
The reverse labels show Thorold Décor, 4 Horne Street, Elsternwick, a business operating from the late 1960s through the mid-1980s, with the site redeveloped in 1987. This gives us a clear hard stop: these posters were framed at least forty years ago, before modern decorative reproductions became common, and these were already treated as objects worth preserving.
The printer:
The margin credit — “Wholly lithographed & produced in Australia by William Brooks & Co. Ltd.” — is critical. William Brooks & Co. was the primary printer handling Tooheys’ original advertising work during Jardine’s active years. Authentic period posters carry this exact credit; later reprints often don’t.
The print & paper:
Close-up inspection shows ink absorbed into the paper fibres, uneven saturation, and organic grain — consistent with traditional commercial colour lithography, not modern offset or digital printing. The paper also shows natural oxidation and age-related foxing that develops over decades.
The size:
The dimensions align with known original Tooheys advertising formats from the period. Reproductions are frequently resized; originals tend to hold true to their original production specifications.
In short
When the framer’s dates, printer’s mark, print method, paper ageing, and format all line up, the evidence points in one direction: these are authentic, period-original commercial lithographs.
