About 4 1/4" x 6 1/2". Looks Victorian age to me, noting in particuler ruffles on subject back row 2nd from left. Appears to me to be young adults of some different nationalities. The girls appear to be of assorted European ancestry. From left the first boy, the one with ruffles, looks like a young Napoleon to me; the middle two likely brothers, and to far right a darker skinned lad with an Indian style collar. If not for the indication it was taken in Massillon, Ohio in the J. C. Baring studio I would guess it to be taken in India. No information on the photographer was found with a search. Also difficult to guess why this group is together, perhaps students at a Bible college but anything I can come up with so far seems against the odds so your guess is as good as mine if not better.

General light age but not bad at all.
