ABSTRACT:
A combined greeting card and decorative music box structure that includes a flat rectangular box formed from a resilient polymerized resin that is removably closed by a cover that on a first side supports a wind-up music producing mechanism within a confined space defined by the box and cover. A second side of the cover removably supports a greeting card. A panel bearing a decorative insignia is pivotally supported from the box, with the panel when in a first position overlying the cover and concealing the greeting card. When the panel is pivoted to a second position the music producing mechanism is actuated and the greeting card is visible. The panel is illustrated as a picture frame that removably supports a picture defined on a dimensionally stable sheet of material.
