It's a tough signature - if it is a signature! It could be written by another person, who might be a dyslexic German, if the title is supposed to be "Bauern" (farmers) and not "Buern". If so, the name could be misspelled too.
The first part of the phrase (G* G*) I think it could be the title of painting ( a name perhaps) , while the word "Bum" could be referred to Umberto Mario Baldassari , an italian futurist painter called Bum.
