Sorry, I don't have any specific information about Bruce's artistic signature. Art signatures vary from person to person, and everyone's signature is unique. If you want an artistic signature, you can find a professional artistic signature designer who can design a unique signature for you according to your needs and preferences.

If you want a simple online tool to design your signature, you can try using some online art signature generators. These tools usually provide options such as font, line thickness and Lian Bi, so that you can create your own signature.

Please note that although I can provide some basic suggestions, I cannot replace professional art signature designers or online art signature generators.
