Inside the gates of Wynwood Walls stands The P.T. Experiment, Peter Tunney’s gallery. Tunney uses a combination of stencils, media and graphics to create artistic masterpieces. The skull, from his previous collection, “Skull Session” is displayed next to “Courage,” a five-foot wide by nine-foot high portrait of the American flag painted on tarp, commemorates the 10th anniversary of 9/11.
