This is another great ad by Levis Again much like the "Go Forth" ad it features
a reading of a poem by Walt Whitman

Pioneers! O Pioneers"
A poem celebrating the great American urge to settle and farm the western prairies

It was during these years that Walt Whitman was writing poems such as "Pioneers! O Pioneers!"
dedicated to America's "youthful, sinewy races," "Western youths" drawn to the wide prairies.
