The First Noel, illustrated by Alice & Martin Provensen. 1959.
Normally I don't scan an entire book, but I did so for this particular one because 1) it's not really that long, 2) the illustrations are amazing, and 3) the story.
Illustrated by the incredibly talented husband-wife team of Alice and Martin Provensen, this book was done during what I consider a highpoint of creativity for them. Around the same time, they illustrated the equally beautiful Homer's The Illiad and the Odyssey from 1956.
