Funny this thread should pop up. I have been collecting the Wilton Yearbooks for some years now on and off, I have almost the entire collection. I am still looking for the 1970-71 (I didnt know when they started exactly, thanx for the answer and description, that helps), and the 1975. I have gotten most off of Ebay, I usually wont pay full price for anything, most have been won for 4-6ish , I have bought 2 or 3 full price when I found them in an out of the way hobby store and new I would have a hard time getting them anywhere else. I stopped at a garage sale just this morning and found the 1982 & 1985 which I have been bidding on for some months but have refused to pay the price. Got these for .50 Cents Each.
Happy Dance. I have found the 1975 one almost impossible to find. Good Luck. I love my collection, it is an endless source of ideas and just good ol browsing for me. Heather
