Here's another example of these advertising pencils, this time for ESSO. The oil can moves up & down to expose/hide the gas pump, which is stationary. The metal barrel is imprinted with "Keystone Oil Co Products".
These pencils were made between the late 40s and the mid 50s when the company went out of business.
Other examples in my collection include Atlantic, McMillan, Mobiloil, RPM and Sohio.
