This is a Church Army Flag Hut Day badge from the year 1917.
The badge was sold, by the Church Army, to raise funds to build temporary huts, in London, to offer cheap accommodation for servicemen on leave(especially Americans)
The pin is rusty and the paper carded flag ( 30 mm wide ) a little frayed and age worn.However, it is fairly firm and still retains it's colour,if a little faded, from over a hundred years ago.
Fairly rare item when you consider the throwaway and fragility nature of these badges.
Good authentic piece of First World War history
Free postage to the UK.
