Because this monkey toy is very popular in the market, other toy manufacturers have also introduced similar products. In order to avoid infringement, most of them changed their clothes and names. From the mid-1960s to the early 1970s, a toy named "Charlie Chimpanzee" sold by street vendors in new york was a similar product. But these models are all the same, and the latecomers have different shapes, which are not as classic as Jolly Chimp.
I hope I can help you. Thank you.
