In my 10+ years of selling and collecting antique European postcards, I've come across this duo three times: one card I own (and their outfit was tinted mint green), one card was in terribly soiled condition, so I passed on it; and then, this card, which shows age around the border but the heart of the image is remarkably well preserved.
The card is a tantalizing mystery. I can't makes out the name under the boy's feet but it looks to be V. G-something from Verdun, France. Are these local children dressed up for carnival costume party or is this two members of a traveling circus show? The outfits look quite Indian to me, or perhaps Middle Eastern. The girl's costume and jewelry have been hand-detailed with silver paint. The boy's shirt and shoes are tinted light pink. A hint of blush on both their cheeks, too. The children look wise beyond their years. Perhaps they were indeed part of a traveling troupe of entertainers, used to performing and in being in the public eye?
I have included direct scans (better color accuracy) and photos. I feel I'm mostly at a loss for words to describe this young couple. Although "just" a sepia photo, the photography is so sharp, you can almost feel the shimmer in the flashy material of their costumes.
Note the K Ltd. insignia inside the stamp box verso. My research pinpoints that as coming from a No. 3A Folding Pocket Kodak in use in from about 1918 until 1936.
SIZE: about 3.5 by 5. 5 inches. Please note that due to the rarity of this postcard, insurance is required.
