I have a collection of calligraphy and paintings. Now I want to know when it was, whether it is true or fake, how much it is worth and how to identify it. Thank you.

Seal: Zhang Yongquan

I only know one person:

Zhang Yongquan is a member of Shandong Calligraphers Association. But I don't know if this one of yours belongs to Shandong Book Association. But even if it is, it is estimated that the economic price is not high, and a few hundred dollars will be the top. . Judging from your picture, it is a typical entertainment work.
