I inherited my Dad's Mad magazines which covered the mid 60s to the early 70s, and my Uncle's, which covered the early 70s to the early 80s, and my collection, which began in 1984 and ran to 1993. I read them all over and over. I learned about the world through the spectre of Mad, it was my primary education.
Of course, it ain't what it used to be and hasn't been for a long time, so I guess I'm not that sad to see it go. It was a different era.
