This series of various faces of men don't depict specific famous guys that I'm aware of, nor do they appear to represent a specific era.  But these five sets are clearly a series with similar builds.  A correct set is a pair of identical heads with 5 and 4 pour holes.  Although they are obviously Japanese imports from the 1950s, none of these shakers are marked with any stamps or labels.  They stand about 3'' in height.
