I've seen these ads somewhere. Even the one with the 60s school photo.
I have a full-page ad for the Amiga 500 that was published in Popular Science. I threw out the magazine but kept that page. It was the December 1987 issue, page 21. I haven't scanned it, but I'll do it when I get a round tuit.
I also have some junk mail that Commodore Canada mailed to me. Some of it really was junk (trying to sell Commosore PCs), but one helped push me to buy my A1200.
