Al Feldstein took over a struggling Mad magazine in 1956 and made it arguable the best humour magazine ever. That’s certainly my view. Mad was the first magazine I can recall reading. When I worked at Pakenham Newsagency while still in high school it was the one magazine I’d read regularly. I loved it. Spy vs. Spy, the back page fold ins and other features were things to read offer and over.
Feldstein died recently. The New York Times has an excellent obituary.
