La chauve-souris

Underground is the place to be, these ultra-cold days in Montreal. I took this photo on the platform at the Berri-UQAM station a few days ago, and only later realized it contained a visual pun.

The poster on the left is for an Opera de Montréal performance of La Chauve-souris, literally, "the bald mouse," or "The Bat" in French, which is Strauss' famous opera, "Die Fledermaus."

But, after all, we're underground, so les chauve-souris are to be expected, yes?
