T. De Witt Talmage, Around the Tea-Table
“ Postal cards are likewise a relief to that large class of persons who by sealed envelope are roused to inquisitiveness. As such a closed letter lies on the mantel-piece unopened, they wonder whom it is from, and what is in it, and they hold it up between them and the light to see what are the indications, and stand close by and look over your shoulder while you read it, and decipher from your looks whether it is a love-letter or a dun. The postal card is immediate relief to them, for they can read for themselves, and can pick up information on various subjects free of charge. ”
