Daffy's launched an unbranded outdoor campaign in subways last month that drove New Yorkers to Twitter for answers.

Johannes Leonardo was tasked by Daffy's to create a campaign targeting young, trendy adults. The project began with an explicit image of a naked man and woman, combined with a snappy tag line and list of Daffy's reduced prices. This picture was then cut into 40 different puzzle pieces, with each piece becoming an unbranded subway poster located in downtown Manhattan and Brooklyn stations.

Each puzzle piece was paired with a camera icon, encouraging passersby to snap a picture -- along with the Twitter hashtag: #UNDERGROUNDPUZZLE.

Instructions and additional clues were posted on a Twitter stream during the month-long campaign.

According to Jan Jacobs, founder of Johannes Leonardo, although the campaign lasted for a month, it took only two weeks for the completed puzzle to be found and posted to Twitter.

"We placed our posters on people's daily commute so they would spot them without having to go search," said Jacobs. "People would find a piece or two and then post them to Twitter. From there, we would aggregate all the found pieces -- enticing the greater online community to work together to collectively solve the puzzle."

There was no incentive offered to the first person to create the 40-piece puzzle; the campaign was launched to solely raise brand awareness to a specific demographic. Not even a gift card?

The final ad, featuring man, woman and the tagline, "More Bang. Less Buck," was revealed in its entirety on Fashion Pulse Daily.
