Our image of Mrs Chisholm is a cropping of the original portrait by A. C. Hayter, whose full name was Angelo Collen Hayter. He painted it in 1852, when his subject was 44 years of age, living in London, and still in the thick of working for much-needed changes in emigration arrangements. The portrait is held by the NSW State Library, and it has been digitalized (reference DG459).
Note: Permission to use the Hayter image here has been obtained from the NSW State Library.
