In the 50s and 60s plastic model kits such as cars, planes or space ships became common in the US. There were also cheap plastic models for the popular market of movie monsters, comic book heroes, and movie and television characters in 1:8 size (about 9 inches or 23 cm in height). These included monsters like Frankenstein, The Wolf Man, Dracula, and the Creature from the Black Lagoon. One of the largest producers of monster figures were the Aurora Plastics Corporation, who produced many thousands figures from each mould. This market disappeared and no firm since has produced anything to match their quantities. Instead smaller (3¾-inch or 10 cm) action figures of have taken over the popular market.
