To say that George Vlosich can work an Etch-a-sketch is a bit of an understatement. In fact, he has become world famous for his abilities, having been featured in scores of magazine and TV interviews.
You can own a Vlosich original starting at $7,500. George also does paintings and sells signed prints. You can learn more at his website.
Incidentally there are a number of other well known Etch-a-sketch artists. Here are links to a few:
Another etch artist is “Etcha” and you can view his (my) work at his new site: http://www.etcha.net (which is only partially complete) or see all of my work at http://www.flickr.com/photos/etcha/
hope you find something there you enjoy.
