ABSTRACT:
A convenient and economical artwork analysis device that visually aids an observer in determining the existence of geometric interrelationships among the artistic elements making up a work of art. The device includes a transparent sheet of synthetic resin material, a plurality of opaque indicia impressed on the sheet presenting a plurality of geometric patterns with small indication circles surrounding and drawing attention to key points of intersection of the indicia. A handle is integral with the sheet for positioning the sheet in order to visually superimpose the indicia on the work of art to aid the observer in determining the existence of and analyzing geometric interrelationships among the artwork elements. In use, the observer holds the device to observe the work of art therethrough and to visually superimpose the indicia thereon.
