Abstract
A picture frame assembly which has an outer frame with an inner frame carried on the outer frame background plate with provisions for easy insertion and removal of image-carrying sheets, such as paintings, photographs and other decorative sheets. The picture frame is unique because of the following features. While the inner frame's bottom and side pieces are adhesively attached, the inner frame's top piece is detachably mounted to the inner frame's side pieces. The inner frame is extended further than the outer frame to allow image-carrying sheets to be inserted into the inner frame in a completely flat vertical orientation. The top piece is attached by the wedging of grooves in the each end of the top piece onto tapered corner connectors extending from the side pieces.
