    Abstract: An improved artist sketch box is described as including a bottom with upstanding walls attached to the bottom generally about the perimeter forming a base compartment, diagonal members affixed within the base compartment further defining the area therein, a lid assembly of approximately the same peripheral configuration as the base compartment hinged to one of the upstanding walls, and as having lid walls attached to the lid assembly adapted for receiving one or more artist panels and a panel board member hinged to the lid assembly to provide access for inserting or removing the artist panels from the lid assembly. The lid assembly pivots about its hinges so that the lid walls and panel board member align with the upstanding walls to form a box.
