Here it is already August and I have received only one postcard this summer. It was sent to me by a European friend who was traveling in Mongolia (as far as I could deduce from the postage stamp) and who simply sent me his greetings and signed his name. The picture in color on the other side was of a desert broken up by some parched hills without any hint of vegetation or sign of life, the name of the place in characters I could not read. Even receiving such an enigmatic card pleased me immensely. This piece of snail mail, I thought, left at the reception desk of a hotel, dropped in a mailbox, or taken to the local post office, made its unknown and most likely arduous journey by truck, train, camel, donkey—or whatever it was— and finally by plane to where I live.
Until a few years ago, hardly a day would go by in the summer without the mailman bringing a postcard from a vacationing friend or acquaintance. Nowadays, you’re bound to get an email enclosing a photograph, or, if your grandchildren are the ones doing the traveling, a brief message telling you that their flight has been delayed or that they have arrived. The terrific thing about postcards was their immense variety. It wasn’t just the Eiffel Tower or the Taj Mahal, or some other famous tourist attraction you were likely to receive in the mail, but also a card with a picture of a roadside diner in Iowa, the biggest hog at some state fair in the South, and even a funeral parlor touting the professional excellence that their customers have come to expect over a hundred years. Almost every business in this country, from a dog photographer to a fancy resort and spa, had a card. In my experience, people in the habit of sending cards could be divided into those who go for the conventional images of famous places and those who delight in sending images whose bad taste guarantees a shock or a laugh.
