Abstract
A picture frame that includes a concealed compartment includes three frame members connected at their ends to form a U-shaped structure and a fourth frame member that is unconnected to the three frame members and to which a picture-bearing panel is affixed, so that when the fourth frame member is removed, it carries with it the picture-bearing panel to reveal the compartment which previously had been concealed behind the picture-bearing panel. Inwardly facing grooves on opposite sides of the picture frame serve as guides for the edges of the picture-bearing panel as it is drawn away from the remainder of the picture frame.
