A solar reactive device is set forth for imparting images on light sensitive paper. Light sensitive paper is positioned within an open container whereupon a positive transparency is positioned thereover and finally a plastic-like cover encloses the contents.

Further utilization of solar light effects clarification of an image imparted via the removed positive transparency.
