Van Gogh began his work relying on the Dutch Masters. He was intrigued by the Masters' ability to have fun with shadow and lightweight. He also found an association in the painting of common events and/or people. For instance, The Potato Eaters captures a small grouping of peasants sitting yourself down for any meal. The painting is dark, yet, light radiates from your faces. This picture amazingly captures the think layer of clouds in the valley at the south of Lake Como, northern Italy. In the above image, the dense cloud hides almost the valley and instead gives off some artificial lights which make town such as an opaque blanket. The village over distance is clearly seen out from the blanket. While I've browsed Google, Yahoo, Bing and Wikipedia, I can not find an answer about why. I've examined those sites of Taylor, Martin, Gibson, Fender and even more manufacturers and they also definitely don't discuss it. I can not even find anybody with a guitar online forum that has speculated about why.
