3x3.25" silvered brass hinged lid case is totally unmarked but 1930s. Front features incised classic image of Mickey Mouse playing banjo as Betty Boop (who wears a rather revealing bikini-like top and belled skirt) dances in rocky nature scene. Original elastic band within. Case shows moderate wear w/some scattered small areas of brass showing through. VG. First example we've seen in our 47 years. From the Maurice Sendak Collection and comes with COA.
