This is the top flat part of an overhead projector - the kind they had in the classrooms at school. Measures 11" square. Lens is sandwiched between two pieces of plexiglass or acrylic on front and back. Frame is hard plastic. Use as overhead projector replacement part or perhaps many other possiblities including making a solar cooker or hot water heater.
Definately not a toy. Wear eye protection when using and don't leave unattended outside. Used. Excellent condition.

Note - Someone asked if there are scratches...... There are two 1/2" straight scratches on the glass side about 3/4" in from the curved corner edge. Actually I never noticed them until the question, and then I looked really closely. Everything else near the center and all over looks very good, smooth and clear. Shouldn't affect use.
