The exhibition, throughout August, will feature enlarged versions of the stamps - due to be issued over the next five years.
Andrew Hammond, from the Royal Mail, said: “We’re delighted that Battersea Library will be displaying our First World War stamps.
"This set of stamps forms part of a wider programme by Royal Mail to commemorate the centenary of the war, helping to tell some of the important and moving stories about the beginning of the conflict in 1914."
The Royal Mail played a significant role in the First World War as part of the General Post Office.
