Abstract
Abstract A picture frame is formed of a transparent front box with rearward projecting rims. Complementary rims on an inner box fit tightly within the rims of the outer box. A downward flap on a rearward edge of an upper rim of the front box holds an upper rim of an inner box and engages a support. Outer sides of U-shaped rims of an inner box engage the rearward rims of the outer box; inner sides are sloped to engage supports. Clamps extend from rims of an inner box into inward cavities in rims of the front box.
