South Australian Army Nurses' Day 1917 souvenir matchbox

Metal matchbox cover produced as a souvenir of South Australian Army Nurses Day on October 27 1917. It is painted on both sides, but much of this has worn off over time.
One face features a central circular area containing a fan of flags representing the Allies, signifying their unity and cooperation during World War One.
Above the flags, the words 'These colors don't run' are written in red, while beneath the flags on a scroll is the phrase 'Dieu Defend Le Droit', which is French for 'God Defend the Right', a motto often associated with military and royal contexts, reinforcing the patriotic theme.
There is a gold border around the central motif and also around the outside of the cover. Between these two lines at the top is the text 'October 27th 1917' and at the bottom 'Army Nurses Day', both in black lettering on a creamy yellow background.
The other matchbox face features an image of a nurse wearing a white veil and a red tippet over her white dress. This is the same image that appears on several souvenirs relating to the day, but is in very poor condition. Beneath the nurse are the words 'God's Angels'.
The thinner central side of the cover is in the worst condition, with the text being virtually illegible. The letters 'C.T' can be seen on the extreme left, perhaps indicating the start of the C.T. & W.A. group who organised the day.
