Asian Art - Ink on Rice Paper Signed

I have two (2) pieces of Asian Art which I believe are Ink on Rice Paper. Both are Landscapes of Rivers/Waterfalls. Both appear in my eye to be Original Art, Not Prints. The Paper is Wrinkled/Krinkly. They are similar in size (visible paper) measuring approx. 26" by 13" and both apparently have the same signature. They are as found including the broken glass on the one piece which I have taped to prevent damage. Both are professionally framed. Seeking information as to the Artist, Age, Desirability and approx. Value. Detailed photographs attached.
