Walker development associate Masami Kawazato spotted this guerrilla sign posted by an anonymous Walker staffer in a back stairwell. “For me that 8 ½ level is the fake-out level,” emails Masami, whose office is in the top floor of the Walker’s Barnes building. “At 8 I get really excited I’m almost to the office after trudging up those steps, and it’s like 8.5 is the teaser before you finally get to 9. Mostly I wanna know who did it!”
