Hi. I'm publishing a book with Cambridge University Press, and I'd like to obtain images from the 1950 publication, "How Red is Your Little Red Schoolhouse," to use in the book Post-WWII chapter. This pamphlet was published by the National Council on American Education (Allen Zoll). I cannot find it. Does anyone know where these booklets might be located? I've checked all of my university databases without luck. I've also checked with the University of Arkansas' library where Zoll's papers are located. They do not have any copies or images of the booklet.
