This metal poster is a combination of the teaser "A" posters from all 4 Avengers movies. The position of the movies is arranged like time passing on a clock: it starts in the top right with The Avengers, then it moves clockwise through Avengers: Age of Ultron, Avengers: Infinity War, and Avengers:Endgame. 

These four movies are the main events in what Marvel Studios calls the "Infinity Saga": a movie arc spanning phases 1,2, and 3 of the Marvel Cinematic Universe. The last of these movies, Avengers: Endgame, is the culmination of a story arc that spans 22 movies and 11 years. 

The poster is painted on 8.5” x 11” or 11" x 17" sheet steel and burned with a laser engraver.
