Hello Judged the case, the remainder of the father and found an old picture ( watercolor on cardboard ), which has seen his grandfather , in his time. Grandpa a little fond of collecting and , characteristically, " slag " is not going , so I'm interested. Determine what kind of artist I did not leave, though looking like he could. Thanks in advance for your help.
