Walking down Avenue de l’Opéra in Paris, there are interesting sights every few steps. This is, after all,  the road that takes one from the Opera House (Palais Garnier) to the Louvre; it’s a major road constructed as part of Georges-Eugène (“Baron”) Haussmann’s late 1800s redesign of Paris.

Around the corner from our hotel and in the centre of the city, this is also home to numerous shops and financial institutions. We passed these tall, double blue doors at least twice daily, and they drew a smile each time.
