Like Tom said, the paint cans of the design you found do come up for sale with some frequency. I mentioned when I did the Mobil COTM thread that on one of my paint cans it said they were manufacturers of paint since 1872. I'm not sure when Mobil stopped marketing it, but I would guess the early 60's. This house paint can is dated 3/60 and is seen less frequently than the SOCONY cans with the larger Pegasus on them. And since I was taking a pic, here is an older dry cleaner can if Tom hadn't seen one of this style before. The 50's can comes up for sale every so often, but this 40's one is a bit more scarce.
