Max Howard Dandelions floor art

[dandelion]

Hi, I have a Max Howard piece of metal floor art that I was told by Max Howard himself was from the early 1980s. The piece is of two dandelions on a large piece of driftwood. I do not have the exact dimensions at hand, but it is approximately 4' high and 3' wide. I'd like to find someone that can give me an idea of the value of this piece. One of the dandelions is missing 1 of the 5 leaves. All else appears to be in original condition.
Thank you!
