    Abstract: A coloring book is formed of a plurality of sheets of card stock removably affixed along one edge to the book binding. An image is printed on the face of the sheet, and a die cut outline of the image circumscribes a portion of the image to a midpoint of the sheet. Parallel fold lines are provided adjacent the top and bottom edges of the sheet, and a third discontinuous fold line is provided midpoint of the sheet from the side edges of the sheet to the die cut image. The coloring book is designed so that the individual sheets may be removed, e.g. after coloring, and folded to form a stand with the colored picture standing upright.
