While looking at the yearbooks I do have, I found this picture inside the 1983-84 Juniata book and thought I'd post it for interest's sake with a screenshot of Juniata-today from Google Maps.
As an update, I only need the 1986-87 and 1987-88 yearbooks to complete my collection/finish my yearbook-search. If anyone's in touch with any former Juniata students, staff, or teachers who could help, please feel free to share this post/thread. Even photocopied pages sent in the mail (I'd happily reimburse for postage) or digital shots shared over email would be most-appreciated.
