Forty Four Presidents by MZA & Maria Sputnik.  Available in hardcover from Garrett County Press.

A brief illustrated history of the U.S. presidency told by the presidents themselves in the style favored by modern social networking web sites, Forty Four Presidents imagines 220 years of presidential succession pancaked into a single moment — documented simultaneously by each commander-in-chief in status updates designed for easy consumption by their Facebook friends. Each status update is accompanied by a jaunty, high-contrast profile picture intended to reflect something of the essential personality (and hotness) of the president.
