This sweet little boy is adorably dressed. He poses for his studio portrait in front of a very nice backdrop painting of the sea. The child is holding on to a hoop toy. He takes extra precaution that the toy won’t roll away by standing on the bottom of the hoop. A note below the image identifies the boy as Otto and the year the photograph was taken (1913). I am not a linguist so I can only guess what language the embossed studio information is written in. My hypothesis is that this photograph was taken in Russia, or possibly Greece. If I am correct, one wonders what a boy with a German name (Otto) is doing in Russia or Greece. Hopefully, a visitor to the Cabinet Card Gallery will be able to identify the language and leave a comment which will solve the mystery.

I’m pretty sure it’s Russian. I think part of it says Moscow Photograph, but I can’t make out some of the letters, also the Russian alphabet lost some of its letters at a certain and they are no longer in use. I believe this has a few of those.
