Two original 1938 National Geographic ads for the Lincoln Zephyr V-12. Each measures 6.75" x 10".

Reverse sides: Pepsodent (with Irium) ad on the left; Spam ad on the right.

My parents drove off in one of these for their wartime honeymoon (using gas ration stamps given as wedding gifts).

Bonus Zephyr: the California Zephyr train whizzes by in the left ad.
