Has 'Patti Clayton' written in pencil on the back

The Exhibit Supply Company issued postcard-sized, thick cards from the 1920s through the 1960s. Their cards were sold for a penny each in arcade machines. These cards were almost always black and white or some type of one-color toned cards. They issued cards of various subjects, but specialized in movie stars, cowboys, pretty girls, baseball players, and other athletes.
Their big size and lack of color has hurt Exhibit cards in collector popularity, but these are some interesting cards and they are generally more available than most early American movie cards.

Exhibit issues are very difficult to checklist because the only way to distinguish between the sets is by very subtle differences. Exhibit cards are almost always blank-backed with very little identifying text on the front. Quite often the only text other than the name of the person on the card is "Made in U.S.A." or "Printed in U.S.A." Sometimes there is more than that, but there is usually not much more.
