From the reference box #32 - a Shell 'Signs of Welcome' tag
. I'm not sure where these tags would have been found; maybe in hotels or at service stations, but I'm guessing it originated in the UK during the 60's.
It gives a list of European countries selling Shell Gasoline & Motor Oil and provides the brand name in each of those regions, "many miles from home, you will never be far from a Shell Service Station"
I like it for the little car graphic and the lovely big, rounded corners!Check out more Reference Box items here.
