After playing the 'viral' game with the release of a shady teaser shot on its Facebook page, Citroen today not only published a second teaser photo but also confirmed its plans to unveil the mystery concept car at the Frankfurt Motor Show. With a little help from Photoshop, we enhanced the image to reveal what looks to be a B-segment hatchback, quite possibly a five-door model with "suicide" rear doors featuring 2CV styling traits.

Since Citroen did not release any details other than that the yet-to-be named concept will be officially revealed on September 15, the opening day of the Frankfurt Show, it's hard to say whether or not the study previews the C2's successor, a new member of the DS family positioned under the all-new DS3 or something different altogether.
