Vintage TWO Yixing Zisha Vases China Etched Mountain Scene Signed Clay Pair

  
Beautiful pair of Chinese Yixing Zisha vases, tall and narrow with heavily etched mountain scenes with trees and houses/huts. Marked on the bases and on one vase, there is an old red and white paper label that reads "Made in China".

These are from an estate and I do not have the history. Probably early 20th century to mid century.
