"...I went to a huge retrospective by Pierre Alechinsky at the Carnegie Museum of Art. It was the first time that I had seen someone who was older and established doing something that was vaguely similar to my little abstract drawings. It gave me this whole new boost of confidence."3
"...I used the library at Carnegie all the time. I was reading a lot. I was really into Dubuffet at the time... the last works that he did were very similar to the little shaped things I was doing...."
The drawings from this time do relate strongly to Dubuffet's late graphic style--which in his case were painted on large sculptures and shaped environments.
Later Haring heard a talk Christo gave in Pittsburgh about his projects that was even more eye opening.
"...The thing I responded to most was [Christo's] belief that art could reach all kinds of people, as opposed to the traditional view, which has art as this elitist thing..."
In the end, Haring's time in Pittsburgh was capped by a solo show at the Pittsburgh Art's and Craft Center-as The Center For The Arts was then known.
Still, I have so many questions. Someone responded on twitter, saying he worked as a janitor at The Center and was actually given permission to paint a bathroom there, which was later painted over. Is this true? Has anyone read Haring's journals? Looks like I should.
