Illustrated by Marvel Studios Head of Visual Development Ryan Meinerding, the poster was available to fans on the convention floor, who could collect three individual posters to create one mega-spread of most of the heroes set to appear in the film.
And it's pretty much makeover central here. There's been a lot of talk about Captain America (Chris Evans)'s brooding new beard, a probable result of his gloomy attitude towards life as spurred on by the events of Captain America: Civil War, which saw him retreat to Wakanda with Bucky in tow.
Also worth nothing is Black Widow (Scarlett Johansson)'s newly blonde do, perhaps a result of the character also having to go into hiding after the last film's events.
Add to that Iron Man's altered new suit, a shinier look for Spider-Man, teenage Groot, and, of course, a full look at big baddie Thanos and his Infinity Gauntlet.
A new trailer will likely follow on the back of Thor: Ragnarok in October, with the film itself set for release 27 April 2018.
