Prince Leonard Bust
From Wikipedia: "The Principality of Hutt River, previously known as the Hutt River Province, is the oldest micronation in Australia. The principality claims to be an independent sovereign state and to have achieved legal status on 21 April 1972, although it remains unrecognised by Australia or other nations.
The principality was founded on 21 April 1970 by Leonard George Casley, who styles himself as Prince Leonard, when he and his associates proclaimed their secession from Western Australia."
The rock bust was "hewn by hand with a small axe by a USA artist named Marc LeBuse". (Source: www.principality-hutt-river.com/visitors/)
