Perhaps the best-known painting in its collection is the large canvas by Adolphe Léon Willette (1857-1926) titled in Latin "Parce Domine" (refering to the antiphon "Parce, Domine, parce populo tuo -- Spare, Lord, spare your people." It was first housed in Le Chat Noir (The Black Cat), a famous late 19th century cabaret. It depicts a fantasy Parisian bohemian scene.
I can't find a satisfactory overall image of it on the Internet, though there are some decent detail images. So I might as well add to that pile with some of my own photos taken in 2015 and earlier this year. That's because Parce Domine has a lot of content, much of it both charming and interesting.
