ESSAI de timbre fiscal sans denomination de valeur, en noir sur petit Feuillet, épreuve d’artiste et épreuve de luxe. PROBABLEMENT UNIQUE. Photo [shown above].Since 1986, various proofs of this beautiful Chancellerie issue have emerged, including those shown below from a Christie’s auction, but they are denominated proofs. The non-denominated essay (or proof) has never been seen again to my knowledge!
