The calling card
If you pay attention, you can see there is something written on the back of the card, pressed hard enough that it makes a slight impression on the front side. Flip the card over—see?
This is her handwriting. This is the handwriting of the owner of the record. If you cannot read it, here is translated what she has written, to remind herself (and you, perhaps):
Mlle. Victor Louise Noémie
Born 13 May 1896
in the 15th Arrondissement
She has underlined her maiden name twice, and underlined it hard—her father’s family name. Her Christian name is Louise. She is thirty-two years old.
