I spotted this on a run the other day, the coolest free library box. This box was next to another free library box which was intended for grownup books while the Waldo box was full of kids books.
Love the reference to the classic Where’s Waldo books, that this box is meant for kids and was built at a child’s height. It’s a bit hard to tell but the Waldo was drawn on a mirror so kids would see themselves as Waldo. Brilliant!
