These are not knock offs but screened prints on canvas of his original work. That is why so many people posting here have the same piece. They will be uniquely different in the screening process, but the painting are essentially the same, and it is real canvas and paint. I have the one with the barn and trees, and I get a ton of compliments on it. These are totally vintage 1970s art, and probably worth $125-$175 in a second-hand store. To me, they are great because hardly anyone has one! You can go to Z-Gallerie and buy garbage paper prints framed for 3X as much or own a fun retro, collectible piece like this! Who is Fadik? I have no idea! Best wishes all.
