Beginning in the early 1950s, Louis Marx and Company sold boxed sets of figures and accessories called playsets, such as "US Army Training Center" and the later "Battleground" sets. A rival manufacturer, the Multiple Plastics Corporation (MPC) also sold plastic figures in various colors with different separate accessories, so the same figures could be kitted out as soldiers (green), farmers, pioneers or cowboys (brown), policemen (blue), ski troopers (white) spacemen (various colors), or American Civil War soldiers in Blue and Gray.
