在拍卖会上为什么一件艺术作品比另外一件能卖得更高的价格,这是长期以来无须费力就能得来的结论。专家认为:对于同样的作品,收藏者愿意花钱收藏有魅力的年轻女人的肖像而不是上年纪的妇女和男人的肖像。水平纹理的画布比垂直纹理的画布更吸引买者;有水的风景画比没有水的风景画卖得要好;裸体的作品优于穿衣的;色彩明亮的作品胜于暗淡的。纽约画商大卫·纳什(David Nash)提出另外一个观察到的现象“带牛的画不能卖”。 Why a piece of art at the auction is higher than the price it can sell is the result of a long period of time that can be obtained without any effort. Experts believe that for the same work, collectors are willing to pay for portraits of attractive young women rather than portraits of older women and men. Horizontal textured canvas is more attractive to buyers than vertical textured canvas; Landscape with water is better than Landscape without water; David Nash, a New York art dealer, put forward another observed phenomenon, “Can not sell with bull.”
