This year marks the 150th anniversary of Clairefontaine, the French company that makes the paper for Quo Vadis planners and notebooks. (If that sounds like a long time, consider the fact that a nearby monastery in the town of Étival-Clairefontaine made vellum and paper before that, in the middle ages.)

The photograph above, taken at a recent event in France, is of Christine Nusse, the great-granddaughter of Clairefontaine founder Jean-Baptiste Bichelberger. Here’s to 150 more years!
