This is an early At Last & Co. coverall. I've kept it stored away since I bought it. The starch is still stiff. There is no discoloration or sun fading. As it's from the earliest period, there's no model number, just "KOVERALL" written on it. The buttons are change buttons. How about it for collectors or those who missed out on it back then? Due to work, it may take a few days to answer questions or ship the item.
