The artist is well known for pursuing the American government over copyright issues and signed very little
This piece came from the Vancouver Art gallery in 1980
He signed two of them and they kept one and this one ended up in an art collectors collection And was verbally authenticated by the gallery for him
We have acquired it from him for a few years ago and Its hard to let go of it because its so beautiful but its time
Google the artist and you will learn so much fascinating information and this particular poster without his signature is a couple thousand dollars, but with the signature is worth much more than we are asking
