The rubbings of Maojia Painting and Calligraphy Institute. Really?

The rubbings of Maojia Painting and Calligraphy Institute are really valuable. It is certain that the original rubbings have collection value, but the new rubbings are not expensive, and the value of portrait rubbings is usually lower than that of calligraphy rubbings. I have just been to Gongyi Grottoes recently, which is owned by both Hu and Han, reflecting the national unity policy of the Northern Wei regime at that time. It is still very representative and valuable.
