Idea 2- On the (now closed) Chowhound cooking site there were a lot of requests for recipes from magazines no longer published, especially Bon Appetit, when recipes were not available anywhere online. Often the requester could describe the magazine cover and approximate year(s). I'm not sure whether the site backissues.com is still in business since my attempts to access it aren't working today. But that or similar sites which feature thumbnails of magazine covers can be a great resource for narrowing down your search.
