I LOVE THIS!
I remember seeing it as a child, but I just rediscovered it through a recent interest in Edward Gorey! There are a few different versions of this I think. I like the men with the mirror, the little skull on the headstone that winks, the stiff but elegant way the people dance, the woman's crazy hat, the mysterious masked villain on the balcony, the gentlemen playing croquet in a rainstorm (!), the helpless waif with the handkerchief wailing in the night wind... in short, everything! It's so full of macabre life and it inspires me to write mysteries of my own! Enjoy!
