“I think he came at 4 a.m.,” Mr. Rosenberg recalled. He checked his security feed for evidence of the elusive artist after seeing the piece the next day. “I went right to my cameras, and they were completely blank,” he said. His tech specialists were stumped: another Banksy mystery.
The mural, “Flower Girl,” showing a girl peering up at a security camera sprouting out of a stock, remained a source of local fascination for years, along with a similar piece on a wall at an adjoining car wash. “Garden Girl” depicts a girl with a watering can looking over a stem sprouting an antenna. That piece remains.
