The key here is to find fellow classmates and find out when their yearbook was issued and if they match. i hope theres an investigative reporter down in Alabama.
It’s been a long time, so maybe someone can ask a student currently in high school when the books actually come out. I remember that it was a big thing to have our pictures taken for the yearbook, but I can’t remember if we actually got them until after December. I think we did, I just can’t remember.
