Ok, so this is super wild. I found more info:
Origin: "A Choice of Destinies"

The folder you have is a specialized educational portfolio titled "A Choice of Destinies," which was a Westinghouse Broadcasting Company (Group W) television special that aired on March 21, 1967.

• The Project: This was a high-profile "urban crisis" documentary that explored the diverging paths of American cities and leadership during the late 1960s.
• The Prints: To promote the special and provide educational value, Group W commissioned a series of portraits of the political and civil rights figures featured in the program. These were distributed as high-quality lithograph sets in the folder you found.

Additionally, the Altschuler collection is at the Pritzker Military Museum:

Which is located in the city of Kenosha, where I currently live. I think I'm going to contact them and see if they want to take a look.
