Little did I know but you're not supposed to take pictures inside La Bourse de Commerce. Fortunately for me, no one insisted that I delete this shot. Although the building is open to the public, it's not really a tourist site. That being said, if you're in the neighborhood (due north from the rue de Rivoli on the rue du Louvre in the 1st arrondissement), go inside and take a peek. The ceiling is covered with a spectacular 19th century fresco depicting global commerce; the images are just so classically European centric that it's kind of a hoot even though it was clearly meant to be monumental and serious.
