Those of you ad folks who’ve been playing in the Twitterverse for the last few years have probably grown familiar with Midwest creative director/writer Jason Fox, or perhaps more so with his Twitter alter ego, @leeclowsbeard. Well, Fox, who has been tweeting out pearls of wisdom under the guise of said TBWA legend’s famous facial hair since 2009, has grown popular enough (25,000+ followers and counting) to merit bitter knockoffs and most significantly, both a book and an app. The title? You guessed it, @leeclowsbeard, which will hit bookshelves on June 12.

To promote the app and book, which you can pre-order here, Mr. Fox offers a slideshow that gives you the history of his Twitter effort. We’ve been told that Lee Clow himself flew Fox out to meet in person before deciding to go ahead and publish the title under the banner of TBWA\Chiat\Day LA’s content innovation studio, Let There Be Dragons.
