Basically, it is worthless, 1800, no more than 3000!
In fact, Xie Deping became famous very early and his qualifications were very old. He participated in the establishment of the book association. But it is difficult to be recognized and accepted by everyone, that is, not to sell money. To put it bluntly, I just don't quite recognize his calligraphy!
I bought a copy of his manuscript six years ago, with more than 40 pages of calligraphy, 2000.
In other words, the market is exploding now, but its value increment is almost zero.
And the liquidity is not good! If you ask the painter or collector in the circle who wants his calligraphy, I will tell you almost everything, free to think!
I don't want to hurt you, play with others!
