O.Henry has his phony confidence man utter a solecism:
"Stocks! No!" roars Mr. Morgan. "It's that picture I sent an agent to Europe to buy. I just thought about it. He cabled me to-day that it ain't to be found in all Italy. I'd pay $50,000 to-morrow for that picture - yes, $75,000. I give the agent a la carte in purchasing it. "

I assume we are to recall "carte blanche".
