Welcome to Oldgas. Assuming this is a real can, (and I have no reason to doubt you), I would think you may have something very unusual or unique. If it is something that never made the market for very long, I think both Quaker Oil and general oil can collectors would be very interested. I could see a Quaker Oil collector wanting the whole case to put in a display stand. I collect Texaco items and if I found a test market can for them, I would be trying hard to get one...or two..or all. LOL. As to value, I can’t help there. You might try putting one on eBay and see how it goes. Hopefully others will weigh in.
