That was the day he patented the first pencil with its own eraser had to be sharpened just like the graphite point. Sold it for 100,000. Because Supreme Court erased it in 1875. Justices ruled that because his pencil combined two existing devices it was not patent worthy after all. The patent was rubbed out, the pencil eraser survives to this day. In a more familiar form as piece of rubber attached by a metal band. Over the years many of our most creative people have relied on the pencil from other son welles to Robert Redford to cbss David Letterman. Despite all the electronic note taking gadgets at our disposal these days. The pencil still has its uses including david reese the professional pencil sharpener.

Osgood were told this painting is an artist as known as lee would sell for tens of thousands of dollars. He was writing on the wall for free. Rita braver joins the issue over whether graffiti is art. It is in fact a National Urban epidemic, spread like some mysterious magic marker pen, spray paint fungus. Remember when graffiti was a scourge. Every public wall is covered with names in obscure kind of print. What was once considered vandalism is being presented in an exhibit at the museum of the city of new york showcasing some who as teenagers left their mark in the 1970s and 80s. Im going to be 59 this year. So looking back, wow, just doesnt seem real. Brendon goes by the street name utura 2000. Chris ellis is known as daze and his real name. They say that early graffiti was all about tagging, figuring out a stylish and distinctive way to write your street name. It was the perfect media for what we were doing because it was vibrant colors, quick, dried fast and enabled you to paint on large scale. Over the years graffiti writers began to embellish their work with more design element, many borrowed from popular culture. All along part of the attraction for these kids including lady pink, was that they were outlaws. With spray paint often stolen as their weapon of choice. Learning how to paint in pitch blackness, your heart in your threat, hear a noise, might be a rat, but you jump out of your sneakers and run down then have to continue painting in the dark. This is not an easy thing. But what many of us never realize is how hard these teenagers worked on their creations. They actually planned out what they were going to put on buildings and trains and buses . It was very common to work on your style and translated in to work in the world. A rare group of little black books essentially sketch books. Also photos and reproductions all collected by the late martin long a painter in his own right who became friend and mentor to many. Young graffiti writers. What do you think that he realized this stuff Worth Holding on to . He believed a real creative value what these kids were doing. He bought in to who they were. He saw them as artists not hoodlums . He really very strongly believed that. Bit others object to glorifying graffiti arguing that its a sign of a city out of control. It is filthy. It is spirit killing. Heather mcdonald who writes about urban policy for the Manhattan Institute says she is angry about the exhibit. It is not focus sufficiently on the corrosive effect that the has on the city. Anybody who could avoid the subways in the 1970s and 80s that could have, did. The exhibit presents graffiti in the context of art. You are suggesting that this isnt art . It is vandalism. It is an appropriation of the publics face or somebodys private property without permission, nobody has a right to do that. It is only graffiti or vandalism if you get arrested. If you get away with it its clearly art. In fact graffiti began to disappear on streets and subways as new york city became more vigilant about cracking down and screening up. But it left a lasting impression on our culture. Itura 20000 is a graphic artist who worked for nike and levi. Lady pink is a painter whose work has been exhibited in several museums. And so is daze and the Graffiti Movement paves the way for world renowned artists who created the famous obama hope poster. In all the trio of pioneers. Were all grateful right now to have had that experience. Because a lot of people wow, thats so cool back then. Yeah, it was. You missed it. The museum says, this is in one of the most popular exhibits in years. Whether you like the work or what it stands for theres no getting away from the fact that all of this was created by the very young. 14yearold or 15yearold. It was done by kids.
