The original oil painting on wood panel by Edgard Maxence (1871–1954), a French Symbolist painter, can be viewed at the Art Gallery of New South Wales in Australia. This unused antique, hard-to-find French postcard art reproduction of "The Book of Peace" from 1913 can tide you over till you get to see the painting in person!
Maxence was a recognized artist in his day. He exhibited in the Salon des Artistes Français from 1894 until 1939, and was active on the salon's committees and juries. Maxence combined a highly trained technique with a taste for medieval and mythical subjects and for hermetic imagery.* Sadly, nowadays, he's almost unknown. One of the truly valuable things about postcards is that these miniature pieces of ephemera have preserved a lot of history and art! Maxence's style captures a very ethereal, spiritual feel; there's such a contrast between the the subject's porcelain ghostly white skin and the dark surroundings. On a non-religious theme, Maxence is famous for beauties shown smoking on Job cigarette advertisement postcards.
This postcard, 3.5 by 5.5 inches, is not as in mint condition as I would like. There are some errant white specks scattered among the black robes as well as a light line that runs through the singer's hand. It looks like a crease but it's not. Wear at the corner tips. I've included a photo taken a bright light, which exaggerates the signs of wear and makes the black robes look lighter than they are. BUT between the direct scan and the photo, you'll have a realistic idea of what you'll receive and in hand you'll be delightfully surprised at the quality and beauty of this card!
Thanks to Wikipedia for this information. I highly recommend you look up Wiki's information about Maxence, if nothing else but to see a photo of the artist wearing 'sabots,' the French version of Dutch wooden shoes.
