对于古旧字画,一般是请一些较为知名的鉴赏家来辨别,而一新作,则有许多画家使用所谓的收藏证书,但这些方法是否安全妥当呢?不见得,因为字画的鉴定不能一人说了算,不同的鉴定人得出的结果可能完全不同;而收藏证书所指的对象也可能被张冠李戴,经实践作者认为有一个方法可对新作起到很好的防伪作用。 For the ancient calligraphy and painting, it is common to ask some of the more well-known connoisseurs to distinguish, and a new work, there are many artists use the so-called certificate of collection, but these methods are safe and proper? Not necessarily, because the identification of calligraphy and painting can not be said alone , The results obtained by different appraisers may be completely different; and the object of the certificate of deposit may also be taken advantage of, and the author believes there is a way for the new appraisal to play a very good role in counterfeiting.
