UPDATED: Marvel Asks: 'Who Are The MYSTERY MEN?'
Update: As pointed out by fan speculation online, some of the characters seen in this teaser image resemble ones seen in Daring Mystery Comics, published by Marvel predecessor Timely Comics from 1940 to 1942. Specifically, the character in the middle of the teaser strongly resembles Golden Age character The Fin. In 2009, novelist and current Black Panther: Man Without Fear writer David Liss made his Marvel Comics debut with Daring Mystery Comics Special #1.Original Story: It's the first of the month, and Marvel Comics is back with their latest enigmatic teaser image. It appears to be illustrated by Patrick Zircher, and features five shadowy figures along with the tagline "Who Are The... Mystery Men" and the date "June 2011." The only text accompanying the image was, as seen in the image, "Who Are The Mystery Men?"
Your guess is as good as ours for this one, but remember that (for whatever it may be worth) there's a seemingly unrelated Dark Horse property called "Mystery Men," created by the Flaming Carrot's Bob Burden, which inspired a 1999 Ben Stiller film. June solicitations are still about six weeks away, but it's a good bet we'll hear more about this project before then.
