I bought this can a few months ago off Ebay. I hadn't ever seen this composite can in all my years of collecting Mobil. I asked the seller if they had any history on it and he explained his dad opened a Mobil station in 1950, and by the later 50's he had went on to be a jobber instead. They were cleaning out the father's estate and found this can in the garage, the only one they came across. Have any other Old Gassers seen this can before? I've always been aware of the later blue and white Mobiland composite quart, which is past my collection focus of 1931-1965. I can certainly say this is a rare can as far as relative availability, especially in the line of later composites. I'm also confident it was produced for the American market as well.
