Solving
The given image is from James Ayers and is called The Rebellious One. But this is not what we are looking for, because we look for the name of Mr. Gud and a cow painting. So if you look further into the gallery called Signature gallery and the listet artists. You will find a man called Trent Gudmundsen. This guy has a painting from a cow called Young Holstein. And this should be the flag:
