Wanted: Looking for École secondaire Confédération, Welland, Yearbooks

I'm looking for a copy, in good used condition, of the École secondaire Confédération, Welland, yearbooks for any/all of the following school years: '79-'80 (80) / '80-'81 (81) / '81-'82 (82) / '82-'83 (83) / '83-'84 (84) I will pick up/meet anywhere in Niagara area at seller's convenience, and I am prepared to pay $100.00 per yearbook under the following conditions (please read carefully): Signatures/messages on the INSIDE front and back covers are to be expected and are fine, but the yearbook must be FULLY intact, with outside front and back covers and ALL original interior pages present and unmarked. Inspection of each yearbook prior to purchase is a must. Please contact me with the year(s) you have available. (Pictures are examples of the covers for '79-'80 (80), '82-'83 (83), and '83-'84 (84). Thank you in advance.
