I'm in love with the "Bestia Parvulus" photographs series by the canadian photographer Pamela Klaffke (prints available here.)
Aren't they a perfect inspiration for Halloween costumes too? A good outfit and an animal mask like those ones are the perfect compromise if you want a 50% charming, 50% creepy effect. Imagine a brigade of these little girls in a deserted street or a park after dark...brrrrrr....great!
I should definitely buy a rabbit mask like that one!
