The Union Oil Company issued 186 in 1948. They were not numbered and no copyright year was printed on the cards. The wording and the Union 76 emblem is located on the bottom left side. However the 1948 issues have different wording in the stamp box which makes it easier to identify. Below is an example of the stampbox that was also repeated on some cards in 1950. The Number following the state name indicates how many card are in that state.
This series can be identified by observing the logo & Stampbox as shown to the side
NOTE: Those with an "*" indicates that the "Made in U.S.A." is a little to the left of the 76 Logo.
