BoingBoing put me on to Top Shelf, a publisher of excellent graphic novels who hold an annual sale I patronise. Last year a stack of kids titles appeared and my son was very impressed, enough that he started seeking other titles by artists like James Kochalka -- whose Sketchbook Diaries are great.
The other day my son said he'd spotted James in the Pirate Penguin Ninja Chicken book he's read every day since it arrived six months ago.
Here's a picture from Kochalka's work
And I like Kochalka's sketches of other artists
But the other thing that got me excited was seeing Rich Koslowski's King in the pic at the top too. Here's The King, which is a great read and I like the music focus in all of the Koslowski I've read
