Bought this because it's so odd, it was buried for 50 years plus, up in New Jersey in a carriage house under some floor boards. I have looked at it under a loop, looks like just ink on stone no dot matrix. I think the stone is soap stone, weighs 42 pounds, 12 by 16, the original etching which is easy to find was done in 1948 by Gerome Kaplin titled "the Arabs" on what I think is a 42 pound piece of soap stone. Never seen anything like it, Sotheby's is checking it out. Figured a Freeper might know.
