Longboy clowns salt and pepper shakers

Most longboy shakers are animals like the classic squirrels or skunks.  Here is an example of a rarer longboy consisting of two identical clowns.  A correct pair should have 3 and 2 pour holes.  The sets are less than 3'' in height and greater than 6'' long.  They have a "TILSO Handpainted Japan" sticker on the bottom.  Circa 1950s.

Below is similar longboy clown set.  I wonder if there is a third set making a series out there?
