Vintage Penn Prints Ancient Cave Paintings Art Prints Chinese 15X12 Set of 3

Estate find. I found these prints at an estate sale, they were framed but they looked like they were stored away and not very well. The frames were awful, unsalvable but I removed the prints from the frames and the prints are very nice. There is a set of 3 Penn Prints ancient cave paintings prints #'s 1, 2 and 4. Prints measure approximately 15X12. One depicts women cooking and milking a cow with a calf and other cows standing near. Another depicts warrior horsemen with bow and arrow and the third is men fishing in boats. I could not leave these behind to be dumped. There is a bit of tape on the back of each from where they were taped to a matt. Please inspect the photos.
