The second is to identify strengths and weaknesses.
The third is appraisal value.
It evaluates the value of a painting and calligraphy work on the basis of distinguishing authenticity from pros and cons.
As for the value of works, it includes appreciation value, cultural relic value, historical value and economic value.
I remember 1995, Hanhai Auction once put out a handwritten scroll of ten poems by Zhang Xian in the Northern Song Dynasty.
This is a vivid historical picture with high appreciation value, cultural relic value, historical value and economic value. It is precious evidence for us to study the history, politics, economy, literature, calligraphy and art of the Song Dynasty.
Before the auction, this painting was appraised by Xu Bangda, Qi Gong, Liu Jiu 'an, Fu Xinian and other famous painting and calligraphy experts. They conducted a comprehensive demonstration from the aspects of painting style techniques, theme, pen and ink interest, ancient costumes, paper and silk materials, historical taboos of using words in poetry, inscriptions and seals, and historical research. They agreed that it was a famous painting by Zhang Xian in the Northern Song Dynasty, an orphan of the world and a national treasure, so they unanimously called on the Palace Museum to pay a large sum of money for it.
As a result, at the auction, the Palace Museum beat everyone and successfully won ten poems at a sky-high price of19.8 million yuan.
