I happen to come across vimeo.com through someones tumblr and found some really cool videos that people are welcome to upload at a high quality. While browsing through the different staff recommended videos I found a video on a wall built by an artist named Lou Dorfsman, who passed away in 2008.
The title of the piece is Gastrotypographicalassemblage, and it was commissioned by CBS to be placed in their cafeteria in 1965. The wall is 33 feet long and 8 feet high, and consists of about 1,450 letters.
It really struck me as a beautiful piece and I was disappointed to find out that it was torn down without much thought. However, an artist had salvaged the piece and stored it poorly for about 20 years before they began to restore it. Many of the letters were worn down beyond repair, and although it took a while, it has recently been opened at London's Kemistry Gallery
