In the 1970s and 80s there were two series of comics I (Rob) loved more than anything- they were team up comics. One featured Batman and any other superhero (or even a villain) as a guest star. That was called "The Brave and the Bold." The other featured Superman and another superhero. That was called "DC Comics Presents."
In 2009, DC Comics Presents issues #1 through #26 were collected in one volume called "DC Showcase Presents" and they were reprinted in black and white for a really low price (between 17 and $20). Since I had sold or given away my DC Comics Presents collection somewhere along the last 30 years, I was excited to reclaim those stories and found them in this great issue.
Some of the heroes Superman had in this include; The Red Tornado (one of my favorites), The Flash, Aquaman, Swamp Thing, Green Lantern, Wonder Woman, Adam Strange, Mr. Miracle, the Atom, Black Lightning, Firestorm, Batgirl, and many more.
It's a classic collection with great stories and great characters and I'm looking forward to reading Volume 2 (which I have waiting for me).
