My latest scan is the Apogee 1973 which is the yearbook for Cardinal Mooney High School in Greece. The school opened in 1962. In this yearbook they have a graduating class of about 340 students. Notice too that they have a photo for every student but the underclass picture are very small. That made this yearbook end up with 200 pages (about 25mb).
Mooney closed suddenly at the end of the 1989 school year. The stated reasons were declining enrollment and financial difficulties. Another problem was that the school had lots of asbestos and it would have cost a lot for the asbestos abatement. Greece Central School District purchased the building and had to clean up the asbestos before they could open as their school.
