A new crop of "Avengers: Age of Ultron" promotional artwork has surfaced on the Twitter feeds of Prophets of Geek and Weeping Angel. The images feature head-on shots of Black Widow, Ultron and the Vision, giving us detailed glimpses of the trio's "Age of Ultron" looks.

Also included in the batch of art are two stylistic mash-up images -- one depicting Tony Stark's Iron Man armor nestled inside the Hulkbuster suit, and another presenting Ultron and Vision as two halves of the same face.

This latest round of promotional art comes after the reveal of Ultron and Hulkbuster images as well as a pair of bio cards for Vision and the film's villain.

"Avengers: Age of Ultron" opens on May 1, 2015.
