The Grey Lady and the Strawberry Snatcher by Molly Bang

Jim Henson's Designs and Doodles: A Muppet Sketchbook by Alison Inches
What an incredible book for Muppet fans! Designs and Doodles collects Henson’s drawings, beginning with a selection from his teenage years. Readers are able to get a glimpse of the evolution of some of the most renowned children’s characters ever created. Designs and Doodles is a fabulous way to learn about one artist’s creative process. The sketches and paintings showcased in the book are phenomenal – early depictions of familiar Muppets (did you know that Oscar the Grouch began life as a rather pinkish-purple furry blob?), fantastical creatures that never made it to the big (or small) screen, cartoons, set design sketches, even dynamic posters and flyers. You can read our review of Jim Henson's Designs and Doodles in its entirety in LFLF Issue 14.
