Here are 2 models of 1990s Vintage CHANEL Sunglasses. 01455 & 0026
Though the item numbers are different, the designs are quite the same.
We are not sure about the reason but I think that the 0026 was released in the early 1990s
while the 01455 was made in the late 1990s.
Because the 01455 has "CE" stamp on their arm..
