Mark Evanier reminds us that there are many older comics pros still very much alive:
http://www.newsfromme.com/archives/2006_12_13.html#012577It's a great list, to which he adds more names (dates are first comics work):
Sam Glanzman (1939), Joe Giella (1945), Al Jaffee (1942), Al Feldstein (1947), John Cassone (1940), Roger Armstrong (1940), Dan Spiegle (1949), Jerry Grandenetti (1946), Sy Barry (1945), Joe Edwards (1942), Ric Estrada (1949), Frank Frazetta (1944), Al Williamson (1948), Harry Harrison (1947), Bill Lignante (1949) and Lee Ames (1940).
And of course, once you get into the early fifties, there are a lot more: Steve Ditko (1953), Jack Davis (1950), Ramona Fradon (1950), Dick Giordano (1951), Mike Esposito (1952), Angelo Torres (1954), Mort Drucker (1951) and a number of others. It's kind of amazing to realize that the first issue of Mad was published almost 55 years ago and of the four stories in that first issue, three were drawn by men who are still around.
