As you know, each animated film coming down the pipeline gets its own Art of book. Pixar's upcoming Brave is no exception, with an Amazon page for the volume sprouting up.
The book will be published by Chronicle Books with a set release date of May 31, 2012. The cover can be seen at the top of this post.
The Art of Brave is being written by someone new to the scene, Jenny Lerew. But a quick IMDb search shows that she is no foreigner to the world of animation, having been a story artist on films such as How to Train Your Dragon, The Road to El Dorado, Lady and the Tramp II, and Flushed Away. She also has a blog, Blackwing Sketchbook, which showcases her simply stunning yet simple illustration work.
Pre-order the book at Amazon now, or go get it at the bookstore in June. It's always worth the read.
