Books of Wonder, Flatiron District, Manhattan
The following is from Books of Wonder’s website as I believe they say it best. “Books of Wonder is New York City's premier store for children's books. Founded in 1980, the store has locations in both Chelsea and the Upper West Side. Books of Wonder features a carefully curated selection of the finest books currently available for young readers as well as vintage, old, rare, and collectible editions for collectors and those looking for long lost treasures. There is also a gallery of original children's book art and limited edition prints.”
They are open 7 days a week. Check their website out for more information about hours and events.
