I recently returned from a trip to England which included visits to the British Museum, the Tower of London, and Blenheim Palace. So I was more than interested to read that I just missed the introduction, at Blenheim Palace, of the new 5 pound polymer note bearing the portrait of Sir Winston Churchill.

The portrait of Churchill on the note bears a remarkable resemblance to the photograph of Churchill taken by the Canadian Armenian photographer Yousuf Karsh on Dec. 30, 1941. Can anyone confirm that the note was modeled on Karsh's photograph?
