The Infinity Gauntlet was made quite recently, but that's not the only time we see the gauntlet. The gauntlet is first shown in the first Thor movie and then later in Thor: Ragnarok.

Infinity War and Endgame are based in part on The Infinity Gauntlet comic miniseries by Jim Starlin, and he spoke about the snap, which is original to his story, in an interview with Mashable.

Taking material from vintage Louis Vuitton bags (along with a few other items), Dishaw has created a high-end Infinity Gauntlet that is both stylish AND functional.
