Yea, I thought if I could see the signature I might be able to read it but I can't. I suspect it was probably a hobbyist painter that is unknown. It's clearly marked Hamburg 1926 so you know it was a German painter. I found a list of German Painters listed in alphabetical order and couldn't find the name there. There was only three that had a first name starting with F and last name starting with G and all of them died before 1926.
