I find branded logos or laser engraved take away the value of a piece. To me they now look like a mass produced item that is cheap in nature. You would never see a high priced piece of artwork with a stamped signature on it. The real deal is usually hand signed giving it authenticity and value in my eyes.Just my take branding irons and lasers add a crisp professional look. But what is or is not professional other than ethics is in the eye and opinion of the beholder.
