I've also bought from this seller and agree with Tom that it's an old original foreign sign. I have one in my collection.....it's a double-sided sign, and both sides are shown in the current listing. It has two "mounting" holes at the top and was designed to be hung from above, so both sides could be viewed. The small five-point shield, painted tin, die-cut Marine Products Mobil sign was displayed the same way.
