Featuring "the world's greatest super-heroes" of Superman, Batman, Robin and the Teen Titans, and the Flash (with two of his major foes, Captain Cold and Heat Wave), this book premiered reprinting some classic tales, with much hope for the future as well, all under a cover by Dick Giordano (though this issue credited as Ernie Chan....it was later revealed to be Mr. Giordano's work in a letter's page).
Here are the stories....and a little historical perspective behind these tales.....
World's Finest Comics #175
The importance of the tale has been discussed somewhat here, and this story led to the second of two Neal Adams tales in World's Finest being reprinted in Super-Team Family #3, and this story was of inspiration to Grant Morrison, who created an evil holographic Justice League with distorted color schemes during his run of the JLA.
Teen Titans #19
So, the lad organized a plan to take on the Teen Titans, which included Robin, Kid Flash, Aqualad and Wonder Girl, with Speedy rejoining the team at this time (originally, Speedy wasn't an original Teen Titan, but their secret origin clarified that, and at the end of the tale, Aqualad left the team to help Aquaman on his quest for his missing wife, Mera).
Speedy and Wonder Girl becoming an item, with the team facing more relevant cases instead of wacky villains, as well as developing its own inner continuity), and along with DC Super-Stars #1 and Super-Team Family #7, featuring Teen Titans reprints...
...which led to a return of the Teen Titans title briefly in the 1970s (picking up with issue #44, and lasting until #53, and introducing the Bumblebee, as well as giving the Joker's Daughter a home, as well as forming the Titans West)...
This was one of the last covers to feature Flash villains for a while (other than one with Grodd, one with the Rogues Gallery and one with Captain Cold), as the title changed direction after Barry and Iris' wedding, and dealt with their relationships, and problems in Central City.
here, and in the future, we'll look back at the rest as time progresses!
