Hello Gary Bounds: You have found out more than I have about the artist and his work. I did not know his first name after searching online for information about him (I am somewhat technologically challenged!). I have six of his paintings, all same size as yours, all painted with scenes in various parts of the country of Brazil. A friend who is native of Brazil says they are realistic depictions of the country in the 1940s. Since we cannot seem to find info on the artist, I would guess that his paintings are worth whatever one would pay for them. Sorry I cannot be of more help.
