Here's another familiar pair of faces - or should that be a singular face? It's Christine and Laurence, who Colette photographed when they were 20. They enjoyed the experience so much that they came back when they were 25 to have it done again.
They've pulled a fiercer expression this time, and so it's easier to tell them apart. Strangely, the most telling difference between them is their lips and their teeth. They've moved in very different directions with their hairstyles, too. Even then, the family likeness is still there.
