This frame is in the form of a Canaletto frame using low relief carved timber, characteristically worked into a shallow ogee profile (or ovolo, as here) at the corners and centres leaving unadorned panels in between. Frames in this style appear on a number of paintings by Arthur Streeton, including The Grampians (Mount Abrupt) 1921, 2013-412 (by John Thallon)
