   • 1922, Sinclair Lewis, “24”, in Babbitt:

     There was an auto salesman in here yesterday that claimed you could always tell a fellow's class by the car he drove, but I says to him, 'Don't be silly,' I says; 'the wisenheimers grab a look at a fellow's nails when they want to tell if he's a tin-horn or a real gent!"'
