A staple of Toronto construction hoardings earlier this decade, to be found wherever citizens were admonished to "Post No Bills," the dissident quartet of Cosby, Gates, Clinton, and Murray has returned. Since the end of December, the stencilled interventions have been sprayed across the city anew, lest their more-recently-conceived New York counterpart hog all the glory.

ca. 2005, the hoardings for Morrison Hall, University College, UofT had a cartoon duck's head with a helpful arrow pointing out its bill.
Around the same time, Val Kilmer was visible pretty much everywhere.
I've always wanted to make a stencil that says POST YO' BILLS...
