Art remains subjective, with no guarantee of universal understanding or appeal among viewers, despite artists' desires to share their creations with the world.

This sentiment is exemplified in a painting by indigenous artist Vincent Namatjira, which features a portrait of Gina Rinehart, Australia's wealthiest individual, among its subjects.

Rinehart reportedly requested the National Gallery of Australia (NGA) to remove her portrait from Namatjira's exhibition "Australia in Colour," which has been on display at the gallery in Canberra since March. The painting consists of 21 individual works combined into a single piece.

Other figures portrayed in the artwork include the late Queen Elizabeth II, American musician Jimi Hendrix, Australian Aboriginal rights activist Vincent Lingiari, and former Prime Minister of Australia Scott Morrison.
