Man-oh-man was this sequel to The Day the Crayon's Quit ever clever. Rather than giving Duncan (crayon owner) reasons for quitting as in the first title, his lost and forgotten crayons explain the reasons they want to return. Each lost/forgotten crayon sends Duncan a postcard expressing his/her desire to return home. Diversity is represented in the variety of unique qualities of the crayons. The hand-written postcards contain drop-shadows, giving the book a three-dimensional quality while the crayon illustrations remain flat but textured. The handwriting on the postcards appear to be written by a child, giving a realistic impression to a fictional tale. There's even a glow-in-the-dark illustration! Fun book filled with sarcasm and wit. I wish I wrote this book. 5 stars, of course.
