Four decades long mystery makes it way to Glenelg Shire

Published on 15 August 2025

A four-decade long mystery has made its way to the Glenelg Shire and community members are invited to take part in the national guessing game.

Martin Shaw’s iconic painting Three Well-known Australians is on display at the Portland Arts Centre and Casterton Town Hall during August and September.

Painted in 1982, the work features three abstract figures (a headless blue person, a seated red person and a green person holding an umbrella) set against a yellow backdrop. Though inspired by three real-life personalities Shaw has never revealed their identities, sparking over four decades of public speculation.

Glenelg Shire Mayor Cr Karen Stephens said it was wonderful to see Glenelg Shire included in the journey of this iconic artwork.

“Since 1983 the painting has been touring Australia, inviting viewers to share their theories. From schoolchildren to Prime Ministers, thousands have contributed their guesses, which are displayed alongside the artwork in letters and visitor books,” she explained.

“Among the most imaginative interpretations is one from Prime Minister Anthony Albanese, who suggested the trio might represent the arrival of colour television in Australia, with the umbrella symbolising the black-and-white era.

“Now it’s Glenelg Shire’s turn to join the guessing game. The mystery is part of the magic, I encourage everyone to come along, take a look, and make their own guess!”

Three Well-known Australians will be on display at the Portland Arts Centre from Friday 8 August to Thursday 28 August, then at Casterton from Monday 1 September to Thursday 18 September.
