Abstract
An artists' canvas is preformed on its rear face with an integral perimetrical and an articulated frame is composed of sectionally hinged rigid pivotally interconnected bars and is disposed flat at the rear face and is movable from a collapsed pointed star shape into a rigid rectangular expanded condition wherein the hinged sections of each bar are in axial alignment and are held in such state by positive locking latches provided at each hinge point. In such expanded condition, the bars fit in the pocket and the expanded frame exerts a constant even stretching force in all directions on the canvas which is held in a taut condition, ready for artistic usage, and which can be removed undamaged from the frame.
