Magnificent Vintage Expressionist Woodcut Etching Artist Proof Thistle Signed. The matte measures 14 1/2" x 15 5/8", the artwork alone is 7 1/4" x 8 3/4". Hand marked in pencil: Artist Proof - Thistle I - artist signed that I can not decipher, looks like S Dan or Soan. I am certain it is by an important known artist. Has the original matte, unframed. Fine clean condition - see detailed photos. I acquired this in a portfolio of wonderful prints and paintings from a local estate of a fine art collector.
