I have scanned fifteen "Tiger" and "Jr. Tiger" yearbooks and compiled into pdf files. The Jr. Tigers and high school yearbooks from 1958-1963 are all in my possession, as were the yearbooks from my high school years of 1967-1970.
At the end of the 1970 school year, our yearbook advisor, Faye Kermeen, set out some boxes of older yearbooks which I believe she threw out. I took a copy of each of the years that were available, which is how I came to get the books from 1958-1963. The earlier years here, 1938, 1949, and 1957, have been acquired from Ebay, etc.
There are three options for viewing and downloading files. The links to the two-page spread are in book form, with left and right pages next to one another. The PDF download link will allow you to view and save the files. The other download options at the Internet Archive links to the main page of the yearbook, with assorted files of varying degrees of value that were generated by the Internet Archive. Clicking on the thumbnails also links to the two-page spread view (when availbable).
