Many of the oil companies handed out these "thank you" plaques over the years, given to associates for X amount of years of doing business with X oil company.
My earlier Mobil ones are from what I estimate to be the mid/late 1940's from Socony-Vacuum, through the 1960's Mobil Corporation. I also have one from Marathon from the 1950's with the running man. I'm positive that the one pictured is in it's original presentation form, laminated to the plaque as shown. I would guess it dates from the 1950's being laminated on the board. All of mine are for at least 5 years of service, another is 10. Not to say that they did these in strictly 5 year increments (as I've seen odd year awards), but I would fathom to guess this one was awarded around 1954 for 25 years of business association. Again, just a guess on that but it fits....
