4H Lazybones, onyx black glaze. DDS7/P7, glazed bottom. Frankoma started to glaze the bottoms of their shakers about 1969. From then until the last one was made these are difficult to date. If the glaze does not date it one can only guess. Also, the Sapulpa clay issues of 1954-1969 can only be dated by glaze. The original year of issue, 1953, on Ada clay is easily dated.
