Redditor /u/Yolka17 shares this photo from her neighborhood in Seattle, Washington. I'm not sure of the precise location of this Little Free Library--the directory indicates that these institutions are numerous in the city.
The design is from Eric Carle's classic picture book The Very Hungry Caterpillar. What happens to this caterpillar? In the light of the moon, a little egg lay on a leaf. When he hatched, he started looking for some books to read. With each passing day for a full week, he found more and more books to read at his local Little Free Library, which he devoured in his cocoon.
