Large 28" Tin Robot Lamp for trade (north beach / telegraph hill)

Hi, I have a 28" one of a kind homemade tin robot lamp for trade.
The arms move up and down and is in great shape.
No rust or missing parts.
I collect a bit of everything including video games, tools, gadgets, jewelry, designer handbags, art, antiques, etc… Let me know what you have to trade to become the next owner of this cool steampunk lamp.
