The seal in the upper right corner is usually a "quotation seal" (a leisure seal), not a "famous seal". Finding a calligrapher's name is like finding a needle in a haystack with a spare chapter. You'd better identify the "seal" stamped under the author's signature. The "Wujiu Wang Seal" is printed on the lower left corner, indicating that the author of this calligraphy work is Wujiu Wang. Of course, whether your collection is the original of Wujiu Wang still needs to be appraised.
