The image of Sock Monkey is a little strange. In the early 20th century, a mother gave monkeys made of Rockford Red Heel socks to her children. The earliest Red Heel socks were first produced by Nielsen knitting factory in Rockford, Illinois in 1890. After that, you may know that socks can be made into such toy monkeys. After that, the sales of Red Heel socks will go up and become more popular.
In 1920, Nielsen knitting company began to make instructions for each pair of red sock monkeys, as well as instructions for other animals. Fox rivermills acquired Nelson knitwear in 1992. Today, craftsmen have been making sock monkeys for generations. This image is thus preserved. The funny image of Sock Monkey also makes him a big IP. The reuse of discarded socks has also been followed by others.
