Now that we're working as a team, Trickster—you see how easily we can beat even two Flashes! 
The Flash #129 is an issue of the series The Flash (Volume 1) with a cover date of June, 1962.
Synopsis for "Double Danger on Earth!"
In the alternate universe that is home to Jay Garrick, aka the Flash, a meteor collides with the sun causing a radioactive burst that threatens to wipe out all life on that Earth. The news spreads fast, and it prompts Jay to consider if he should try and save his world as Jay Garrick, radiation expert, or as the Flash. When contemplating on getting the help of Barry Allen, the Flash of the neighboring universe, Jay begins to reminisces with his wife Joan about his adventures with the Justice Society of America.
Later the next day, Jay learns of a special metal found in a meteor that crashed in the Arizona desert that can absorb the radiation. However, when Jay arrives on the scene he finds that the meteor has disappeared. He deduces that a similar meteor may have somehow existed in a parallel world, existing next to their own. Going into action as the Flash, Jay uses his super-speed to change his vibrational atunement, so he appears on that other world.
While on the alternate world that is home to Barry Allen, Barry meets up with his girlfriend Iris West to go to the Picture News costume ball. Barry has decided to go dressed as the Flash, and has to remind himself to act as he normally would as Barry Allen so as not to expose his secret identity. There Barry notices that a number of the attendees are dressed up as a number of his foes. However, not all of them are reasonable facsimiles, two of them — namely Captain Cold and The Trickster — are the genuine articles and have both come independently to steal the charitable donations being collected. While the two criminals quarrel over who gets the loot, Jay Garrick arrives in his Flash outfit having heard from Barry's landlady that he'd be attending the party.
Jay attempts to stop the Trickster and Captain Cold, however the two crooks begin working together to trip up this alternate Flash and the Trickster escapes with the loot with Captain Cold trailing not far behind. While inside the ball, Barry and Iris notice that it's past midnight and the organizers have not announced how much was raised for charity. When Barry goes to check it out he sees the aftermath of the battle and learns from Jay about the Trickster and Captain Cold's theft of the money. The two speedsters then race after the crooks.
Outside they find that Captain Cold and Trickster are still fighting over the loot and try to use this division to their advantage. However, the two crooks begin working together and realize they make a pretty good team when they pool their resources together and trap both Flash's in blocks of ice. Breaking free from their ice prisons, Jay and Barry find the crooks are gone without a trace. Jay tells Berry why he has come to Barry's world and Barry turns down the offer to aid Jay because he must search for Captain Cold and the Trickster. Returning to the party, Barry (pretending once more to be his meek alter ego in a Flash costume) tells Iris what happened.
Jay races to Arizona where he meets with representatives of the crater museum and learns that a meteor of the same composition exists on this Earth as well. Racing to the spot, Jay uses his speed powers to unearth the meteor and break it down into component parts for easier transport back to Central City where he hopes to transport them back to his own world. As Jay's exploits make national headlines, Barry is no closer to capturing Captain Cold and the Trickster. However, Barry comes up with an idea on how to lure the two crooks out of hiding.
While Jay has setup a vibrator-transporter device to transport the meteors components to his world, Barry approaches Jay with the idea and the Flash's of two worlds agree to work together to capture the two crooks. They plant a story in the Picture News about how the meteor fragments contain a fortune in diamonds, and sure enough the story brings Captain Cold and the Trickster out of hiding. During the attack it turns out that the Trickster they are fighting is merely one of Captain Cold's ice-mirages and that the Captain had stolen the fake diamonds and retreated. Barry follows after Captain Cold leaving a trail for Jay to follow.
While Flash distracts Captain Cold and the Trickster, Jay speeds into the room and quickly turn the two crooks as they are firing their weapons so that they strike each other instead of Barry. With Captain Cold and the Trickster defeated and turned over to the authorities, Jay and Barry finish transporting the meteor ore to Jay's universe. There, the two Scarlet Speedsters load up rockets full of the precious metal and launch them out into space where they deflect the harmful radiation and save Jay's world. After, Barry expresses his concern that the same threat my yet threaten his own world, however Jay has thought of this and had the foresight to examine the composition of the meteor fragments and come up with a means of creating a synthetic version of the ore so that when the same event happens on Barry's world sometime later, scientists of that world can prevent any threat to their world as well.
