University of Pittsburgh Time Schedule of Classes Second Semester 1940-1941

I would like to know the value of the "University of Pittsburgh Time Schedule of Classes Second Semester 1940-1941" that I recently came across while sifting through some old sheet music that was donated to her church rummage sale. The booklet is 28 pages cover-to-cover, and (at least in my opinion) in impeccable condition for its age. Although it is extremely dusty, the only other problems I see are 3 pencil lines underlining Physics classes on page 13 and some very slight wrinkling throughout the booklet. Other than that, there really doesn't seem to be anything wrong with it. I imagine that, it being a time schedule, it would have been extremely worn down from handling by students, therefore I'm curious as to how rare it is to find one of these in this condition. The staples are secure and the pages are still firmly attached without any tears and minimal wear on the binding. It also has tucked in between pages 24 and 25 an Engineering study card with a blank schedule chart printed on the back, looks to be fairly untouched.
