Most likely you’ve heard of the little free library, a book-sharing box that anyone can install in their front yard to encourage passersby to either take a book or donate one. The next generation of little libraries? The Little Free Art Gallery. This new creative trend is rooted in the same magnanimous spirit, but instead of books being shared it’s pint-sized art—and by art, I mean anything creative: paintings, drawings, pottery, yarn works, doodles, even painted rocks. The concept is simple: leave small art, take small art, or just enjoy.
