Unusual historical date format

A friend has a photo of relative from 1901, and both the birth and photo date (printed in the photo presumably from writing on the negative) are in the format dd/mm.yy - A stroke between day and month, and a dot between month and year. I couldn't find anything about that forat with some cursory googling. Has anybody encountered this format before or know anything about it?
