I have 2 Henri Jourdain etchings that belonged to my great-aunt and were purchased approximately late 1930’s. A sticker on the back says “Original Etching in Color by Jourdain, Signed Artist Proof, Edition Limited” the title of 1 of the works is “Entrance to the Cha???” - can’t read the last letters. I would like to know what these are worth. What is their value?
