WW1 Patriotic Tank Fundraising Badge, made of printed textile.

WW1 Patriotic Tank Fundraising Badge , well made and amazing survivor appears to be made from a small section of printed textile.
This rare World War One patriotic badge proudly features a detailed image of a British Mark IV tank, emblazoned with “I HAVE HELPED.” Worn by donors who contributed—often a few shillings—to local fundraising drives supporting the war effort, these badges symbolized community backing for producing or adopting tanks in 1917.
