This is a rare collection of oil/grease that belonged to a salesman that I believe went from business to business explaining his products. Comes with 4 cases of sample oils/grease and also the license plate that belonged to the salesman. I do also have a vintage Jacket the salesman wore while trying to make his sales. Im not 100%sure on a date but was thinking anywhere from late 70s to early 90s but im honestly not sure. If you have any extra information please send me a message because I would love to learn more. Also if you have any questions or need additional photos please let me know. Thanks for looking!
