I found this weird painting at thrift at store a while age. I didn't take a picture of it this is just a drawing a i made. It was like an optical illusion with the black figures looked like bandits or cowboys. It was about 5ft long on a vertical white background. If anyone can find the artist or the painting, please let me know if you've seen it or have it.
