Linda Barry combines funny comics, drawings, and text in a book for adults about how to get your drawing juices flowing. There's how tos are more for an adult who just wants to get started drawing. Her own comics and art are what is really inspiring for me! I also enjoy her commentary and questioning about the drawing process and creativity. In one comic the dialogue says, "If you use coloring books past the age of ten, you will wreck your imagination forever. Who says? All the scientists. Just warnin' ya."
"When you are little you will draw pictures for no reason.
What does a line do? It's not something that you are good at or bad at. It's something else.
You move your hand and you scribble all you want and it feels very good. I can remember that feeling.
What makes us start drawing?
What makes us stop?"
I think this book is probably more for adults, as some of the pages have some adult-like things on them-- such as a monkey smoking cigarettes. However, most of the pages you could show your children who are aspiring comic artists.
Here are some of the pages from her book Picture This.
