I still own all my 70's MAD's and more from my childhood, plus all the paperback ones too...
I'm surprised todays MAD is still running Don Martin cartoons? as he died around a decade ago, not long after leaving MAD and bringing out his own comic "Don Martin".
Don was my fave artist, you can't ignore the flared nostrils and folded-over feet on just about every character he drew.
I bought many of the 'specials' that were solely a Don Martin, Sergio Aragones, Spy'vs'Spy or Dave Berg issue etc...
Too many here too mention ;-)
