Now, technically the JLA had two appearances before this issue. Superman I#149 is an imaginary yarn and therefore not in canon, while Superman's Girlfriend Lois Lane#29 is more of a cameo.
Here a small time hood named Pete Ricketts ends up getting his grubby hands on the Cyberniary, a device that allows one to control a person's mind totally. Which is just laying outside in a garbage pile, as one does. Pete's first idea to test this out on the JLA and when it works, that's when the good ideas dry up.
Yeah, Pete then decides, since he now as the world's greatest heroes at his total beck and call, why not hire them out to the highest bidder for a small fee? Snapper Carr ends up the saving the day with Dr. Destiny's old gear and Pete ends up in the slammer.
