These remind me of old fashion signs or wooden plaques you might find hanging on the walls in old homes, especially in the kitchen or above hallway doors. The shakers sit on a metal stand for display. There are two slight variations - the shakers photographed above have smooth edges, while the shakers below have jagged edges.
The shakers sets stand about 3'' on the stand and a correct set should have 3 and 2 pour holes. Circa 1960s.
