Estetyka was one of the most important model car manufacturers in Poland in the 1970s and 1980s. The company based in Warsaw produced plastic models in 1/43rd and 1/50th scale. Models of two contemporary Polish cars -Fiat 126p and FSO Polonez- as well as a Ursus tractor were manufactured in various colours, but as well as many other Eastern European manufacturers, Estetyka also produced plastic copies of model cars made in Western Europe by companies such as Matchbox ('Models of Yesteryear', 'King Size') and Politoys.
