Failed poster explained here, failed shirt not explained here.
Another Shutterstock incident. Fortunately, the explanation is simple: the design was copied off by hand. If you look closely, you'll find it's not a printed copy of the original design. It's not very close, either. So I guess the painter was given a printed copy that had the Shutterstock logo and he did a mediocre job of painting it on the wall. Copyright logo included.
