Your guess is as good as mine. Or better, because I'm thinking mutant teapot is probably not the right answer.
My friends Heather and Don spent the weekend in Quebec city a week ago, at the Auberge Saint-Antoine. They stayed in a room with a Quebec 17th century theme, and this thing was on the window ledge. (Don took the pictures.) We have asked some likely people, including my clever and knowledgeable friend Dr. Philippe Mailhot, director of the Saint Boniface Museum, what it might be, with no luck.
So what about it, history buffs?
