Faeries.

Faeries. Brian Froud and Alan Lee. New York: Harry N. Abrams, Inc. 1978. There was a spate of this sort of book in the late 70’s, and I didn’t pay much attention to them, except for the one about unicorns. I always through it would be a bit twee, but this is actually is researched and has creepy drawings of the wrong sort of fairies, and notes about a variety of related creatures.
