The company La Parisienne de Photographie is in charge of digitizing the city’s photographic heritage. Checking out its website has been open to the public but not so, of course, reproducing its images. Now, it has created a special collection of prints to buy called Paris en Images. It’s searchable by subject, arrondissement or photographer. You’re free to choose from 50,000 goodies and a simple print costs just €20 (a framed one is €50).
