Marvel Studios concept artist Ryan Meinerding shared an unused design of the Winter Soldier's (Sebastian Stan) mask and metal arm from Captain America: The Winter Soldier.

"Unused Winter Soldier mask from Captain America: The Winter Soldier," Meinerding wrote on Instagram. Unlike the final version of the mask seen in the film, this face covering does not shield Bucky's cheeks. The arm is also more uneven and notched, as opposed to the smooth version he dons throughout the Marvel Cinematic Universe (MCU).
