Martin Mazorra and Michael Houston co-founded Cannonball Press in 1999 as an alternative press publishing both their own prints and those of emerging artists. They began by publishing only affordable black-and-white woodcuts, all of which are available online. They also collaborate on large-scale (10 x 20 ft.) collages made entirely from oversized woodcuts on canvas. Historically, woodcuts were made to communicate issues to the masses, and Mazorra and Houston have addressed themes of labor, demolition derbies, and excess.
