"Hurry up," called Mike. "It's getting late."
"This is a mistake," called Louis. "Here's one that's a mistake."
"How come, Louis?"
"Well, look at it. You can see for yourself. The guy made a mistake."
"What does it read on the back? Hurry, we can't waste no more time."
"It reads 'Up, Down and Across' or something. It's a mistake though." Louis remained eyeing the canvas raptly. "It ain't finished, Mike. We ought to send it back."
"Let's see, Louis." Time out for critical inspection. "You're right. It is a mistake. 'Up, Down and Across,' you said. Well, we'll let it ride. It's not our fault. What's the name of the guy?"
"Bert Elliott," called Louis. A laugh followed. Louis turned to me and my friend.
"You see this?" he said. "I get it now. That's the Wrigley Building over there. What do you know about that?"
Louis seized his sides and doubled up. Mr. Elliott, beside me, cleared his throat and glanced apprehensively at his canvas.
