This is a vintage postcard booklet:

• From Lincoln's New Salem State Park, Illinois, a reconstructed frontier village where Lincoln lived in his twenties, from 1831-37.

• Intact booklet, all pages still attached

• 15 different postcards with an explanation on the back of each one

• No markings

• Creased and weathered from age

My parents and 4 older brothers lived in Illinois in the 1940s and early 1950s. I'm guessing they bought this booklet when visiting the park during that time.
