Frank Cho has been making ballpoint pen drawings purely for himself for over two decades. This is the first time that these rarely seen works have been captured in a dedicated volume. Compiled here are his favorites, many which were done specially for this book. Most pieces are shown in four stages and accompanied by Cho's commentary to reveal his process. Included within the book are visual guides for drawing anatomy and body parts, plus a short interview where Cho discusses his working methods and answers the most common questions that he receives online.
