My folks lived on the Aboriginal communities in the Northern Territory when Western Desert Aboriginal art started to make the transition to its saleable form in the early 70s. They worked closely with and were friends with Geoff Bardon-the guy who was became known as the mid-wife of Aboriginal art (because he assisted the tribes in giving birth to it in its commercial form).

Unfortunately, mum was very sick when she was pregnant with me and couldn't stay on the settlement as the medical resources to cater for her weren't available.
So, not an experience of mine directly, but the background of Papunya and Yuendemu loom large in the folklore of the nuclear family.
