Looking straight out of central casting--what a gang of chefs! Seems perhaps they've been out foraging, with sprigs of herbs in hand here and there, though perhaps that was as for the sake of the photo, as they've got their (very lovely) whites on. Not surprisingly, only one woman among them, who looks a bit as if hiding in the grass!  Surely European, I might guess French--perhaps marking the occasion of a first Michelin star! Pretty fabulous. 

Overall: 11" x 10". Photo itself: 9 5/8" x 7 5/8". Earlyish 20th century I believe, mounted to card. Toning as evident, but in overall good condition.
