What appears to be promotional art for "Batman v Superman: Dawn of Justice" has surfaced online, featuring the title characters in both full-body shots and stylized show-off posters. If official, the images will most likely appear on a variety of products, from backpacks and posters to lunch boxes and folders.

The art began appearing late Thursday on a number of websites, including SneekPeek.ca, dclivefeed and Imgur.

Additionally, Latino Review's Umberto Gonzalez has posted concept art for the Batwing vehicle used in the film and glimpsed in the trailer.

RT! #EXCLUSIVE! #AskElMayimbe Your first detailed look at the #BATWING from #BatmanvSuperman! That's the logo from my new outlet watermaked on bottom right. For now we're just a symbol. "People need dramatic examples to shake them out of apathy and I can't do that as Bruce Wayne. As a man, I'm flesh and blood, I can be ignored, I can be destroyed; but as a symbol...as a symbol I can be incorruptible, I can be everlasting." #Batman #HH #dccu #dccomics #dc #dcmovie A photo posted by Umberto Gonzalez (@umbertogonzalez) on Apr 30, 2015 at 7:06pm PDT
