Is cardboard calligraphy worth collecting?

Judging from the current China market, except for a few influential artists in China, others' cardboard paintings are basically of no collection value. The collection of paintings first depends on the identity of the artist. This artist has been listed as the first in the art history of China, and ordinary painters have little collection value, so they need to be carefully collected. At present, many rice papers are machine-made, and the fiber segments of the machine are not durable. At present, board machine on the market is all machine-made paper, which has almost no collection value.
