A different kind of thimble collector. Sorry the print is so small; enlarging the image even a little bit was distorting the type and making it more unreadable.
Apparently, the 50,000th silver thimble collected by the Silver Thimble Fund is still around somewhere, as it was on display at a Women and War exhibition at the Imperial War Museum, London, back in 2004.
