Description
Three color 7 3/4″ x 11 3/4″ ad for their Summer Oil. In the days before Multi-garage Oils drivers needed to change their oil seasonally and Mobil laid claim to producing the “World’s largest-selling Summer Oil”. The ad has a picture of a lady who is smiling as she stands next to her dog who may or may not be smiling. There is a smaller picture of a service station attendant who is leaning into the engine compartment of a car to insert a quart of oil.
