I observed these charming flame robins when staying at Blackheath, Blue Mountains, NSW, Australia. There are two canvases - a diptych. You can arrange them side by side or vertical (see photo) = overall dimensions with no gap would change to 81 (h) x 51cm (w). You can also display a diptych ( 2 panels) with a larger gap in between, to occupy a larger wall space.
The base colour is a calming powder blue/grey.
