A billboard featuring a picture of former U.S. president George W. Bush and the tagline 'Miss me yet?' left residents of Minnesota wondering what it meant and who paid to have it erected.

A billboard featuring a picture of former President George W. Bush and the tagline 'Miss me yet?' left residents of Minnesota wondering what it meant and who paid to have it erected.

Speculation was rife on blogs on Monday and Tuesday as to whether the roadside sign was an indictment of President Obama's performance so far or a reminder of Bush's unpopularity.

Nobody has claimed the billboard, located on Interstate 35 near Wyoming, Minn., but the media flurry surrounding it is likely to dig up the purchaser sooner rather than later.

The picture of the billboard was widely circulated via e-mail forwards, and many dismissed it as a Photoshop job.

But, according to an eyewitness interviewed on National Public Radio, the billboard really exists and questions of its origin abound.
