Brass Sailboat Artist Signed Brutalist MCM on Driftwood Boat Vintage Gorgeous JG

I have not been able to figure out the artist on this gorgeous boat. The initials JG are signed on the back of the sail. (pictured) This comes with the all the glorious patina that has come with time. The pictures say more than me. I have included the measurements in the photos with the measuring tape. Pictures are part of the description. 1 day processing on all orders except Sundays. Smoke free home. Videos will be included when at all possible.
