One of my favorite picture books is The Mysteries of Harris Burdick by Chris Van Allsburg.
This book contains various drawings with titles and captions to inspire a story. The idea is that the reader is left open to devise his or her own narratives from these pictures, captions and titles.
Not only does this book provide several different story possibilities, but the drawings alone are enough to inspire a writer for dozens of stories apiece. The art is dark and haunting and beautiful. But before I get carried away, I will let the pictures speak for themselves.
