The legend was that Frank Lloyd Wright would on occasion just show up at his previous clients finished FLW homes, and present them with certain furniture or art objects that he felt "belonged" in that house. As if he was still controlling their architectural and decorative lifestyles long after the fact.
He would later send them a bill for these "thoughtfull unsolicited gifts".
