Proof of Barre from his personal estate. Barre kept 2 sheets of each value underlined by the printers name "Typographie Ernest Meyer, Paris". Barre dispersed one set, the other stayed in his possesion, but he cut off this name and only the line could still be seen which we can find only with 2, 5, 20 and 80 lepta, so this block is unique. A very important item to display the full story of the procedure of the production of the Large Hermes Heads
