American Plastic Bricks were manufactured by the Elgo Plastics Co. of Chicago in the 1950s. The sets were marketed by Elgo and by Halsam, another Chicago company. The plastic bricks were based upon the wooden American Bricks sold by Halsam for many years earlier. Halsam also sold American Logs, which were similar to Lincoln Logs, but square instead of round.
The American Plastic Bricks were bright red in color with white plastic doors, windows and trim pieces as well as green cardboard roofing. The plastic bricks did not hold together as well as the earlier wood bricks, but the plastic doors and windows were an improvement over the cardboard doors and windows used in the wooden sets.
