It shows a man harvesting something (presumably shellfish or crabs, or possibly even birds' eggs) from a pebbly beach.
The man is wearing a cap.
There are at least two other men behind him, apparently engaged on the same task.
I think the picture was taken in France.
This is a SMALL photograph - 3 1/2" x 2 1/2" approx (9 cm x 6 cm).
