"The Aboriginal whose head is depicted on this medal and others struck, both in Australia and overseas in the later part of the 19th century, was known as Ricketty Dick. This Australian native was born about 1798 and died in June 1863. He was well known to people who travelled along the New South Head Road on their way to Watsons Bay. He camped on a dry patch of ground in the swamps of Rose Bay ... In his later years ... was looked after by W.C. Wentworth." -- Quoted from: Australian commemorative medals and medalets from 1788 / L.J. Carlisle. Sydney : B & C Press, 1983, p.13.
