Recently I bought a set of the French encyclopedia-style books Larousse Mensuel Illustré, encompassing the years 1907 to 1925.
They are fascinating books, packed with incredible illustrations of all sorts of things, from crazy contraptions to famous people.
They are also incredibly heavy!!
Tucked inside one of the volumes was this photograph...
It has a French studio name on the back, so it could have been the person who once owned these books.
I hope so, that would be brilliant.
But like any found photo, the identity of the person will forever remain a mystery.
I have to say though... she does look a little bit like Björk!!
