First two photos below show two color variations of a man and woman hanging off the sides of baskets. Some of their features give them an Asian look. Then the next two photos show two variations of similar shakers, only these are two men hanging off of barrels.
All four of these shakers are stamped on the bottom in red "Copyright M.K.". I'm not sure what M.K. stands for, but they are clearing Japanese imports from the 1950s. Each shaker depicted here has 3 holes. They stand about 2.75'' in height. I was tempted to call these shakers a series, and I think I still might especially if we ever find the top people in a different pose as the two men below are in different poses. Besides the shapes, the color schemes are also similar with polka-dot prints on at least some clothes on each set.
