The flight was arranged for December 1951 to celebrate the 50th Jubilee of Australia. The stamps on the front cover are all cancelled on 7 December at Canberra and on the reverse in order of arrival - Sydney 7th, Brisbane 7th, Darwin 8th, Perth 9th, Adelaide 10th, Melbourne 10th, Hobart 10th and finally back to Canberra 10th.
Actual cover is pictured. It has slight rust marks on the front however it is undamaged.
I am happy to combine postage for multiple purchases.
