Founded in 1901: the Aetna Toy Animal Co. in New York. From 1906 till 1915 they sold the Aetna-bear, which originally was called the Keystone-bear. Wholesale dealer George Borgfeldt & Co. was the exclusive sales agent. Later the company was called Aetna Doll and Toy Co. In 1919 E.I. Horsmann Co. from New York took over the company.
The Aetna Toy Animal Company marked their Teddy Bears with a black, printed, oval line around their name, which was placed on the right feet.
Teddy Bears from Aetna are very rare, especially outside the USA, because the company only made bears for a couple of years.
