I realized that I'd never compete a run of some of my favorite DC titles that go back into the Golden Age, so I've set the goal of a complete run of a title published during my lifetime (April 1962). I recently got the last Action I needed - thanks, Chip! - so now I have complete 4/62-present runs of Action, Flash, Jimmy Olsen, Superboy, Superman, and World's Finest.
I like this idea - I've been slowly trying to pick up a copy of everything published during the month I was born, but this gives me something to shoot for if I ever finish my birth month set.
Not a bad set to look for. What month would that be? And you are going by cover dates?
Dec of 77. Decided to go by cover dates, even though I know those weren't necessarily the ones on the stands that month.
