How do you get a huge painting shipped to Brazil? Kurt makes me a sturdy crate, that's how we do it!
What you can't see is that on the end pieces, there is a disk that fits inside of the tube that the painting is rolled on. That way the painting is completely suspended without touching the sides. completely protected.
Below shows the foam board over the painting. He than places heavy shipping cardboard over that.
With the heart of a minimalist who paints complicated.
