Fan celebrating the first flight from England to Australia

On 10 December 1919, the Smith brothers landed in Darwin having completed the first successful flight from Britain to Australia: a journey that took twenty seven days and twenty hours. Celebrations took place in Adelaide upon the brothers’ return and many people kept souvenirs like this one.
The balloon shaped cardboard fan has a scallop at bottom and is stapled to long, narrow wooden dowel (light, natural colour). The front of the fan says "AERIAL FLIGHT/ENGLAND TO AUSTRALIA,/1919./Capt Sir Ross Smith, KBE, MC, DFC/ Lieut Sir Keith Smith, KBE/ Sergt J M Bennett/ (Air Force Medal and Bar)/ Sergt W H Shiers/ (Air Force Medal and Bar)"
A map of their flight from London to Darwin with all their stopping points runs through the middle. In the top right side is a portrait photo of "Capt Sir Ross Smith MC DFC KBE" and in the lower left side is a similar portrait of "Lieut Sir Keith Smith KBE". To the right of this is a list of the stopping points & the dates, with the Start from London on Nov 12 to the Arrival in Darwin on Dec 10. The reverse side of the fan has an advertisement for a department store "JOHN MARTIN & CO LTD/ Busy! Busy! always Busy!" This is followed by 2 black and white sketches of the store and written underneath each is the BIG STORE/ "Where your Money goes FARTHEST". On the left it says RUNDLE ST, on the right ADELAIDE.
