DCCP was the long-running team-up comic featuring Siegel & Shuster's creation Superman and a good percentage of the DC universe. It was a book I enjoyed quite a bit, as I like the more obscure characters in the DC universe, and this was the first place I saw a lot of them, especially during the period that they ran "Whatever Happened to..." as a back-up, catching up on characters who hadn't been seen in years.
I picked up the book for a couple of years in the early 1980s, and subsequently picked up a few back-issues from earlier and later than the run I had, based on what looked interesting. I could probably stand to get rid of about half of what I have, but at the same time I really should go over the issues I don't have and decide which I want based on the creators or characters, which would probably bring it back up to as many issues.
Noteworthy in the 97 issue run:
#26 - the preview of New Teen Titans, much more about that series later, and a good Green Lantern team-up
#43 - Curt Swan, Paul Levitz, the Legion of Super-Heroes,
#59 - Superman and the Substitute Heroes against Ambush Bug, probably my favourite of the Ambush Bug stories. I espcially liked Giffen's pseudo-Shuster Superman.
#84 - Kirby and Toth bring you Superman and the Challengers of the Unknown.
#85 - A sidenote to Alan Moore's SWAMP THING run, with art by Rick Veitch and Al Williamson.
