Vintage Advertising Ballpoint Pen - Standard Oil Company - Greeley CO. It is in nice physical condition as shown in the photos, it does show wear and tear from use and age. It is from a local collection and most of the pens were from the 1940's thru the 1960's. The pens may need new ink cartridges if you want to use them. It does function as designed, push the top to have the ball point come out, then click it again to make it go back in. Please look at all the photos, what you see is what you are buying. Thank you.
