That looks like "cargo cult" thinking. People bought the carte de visite (French for "business card") images because of the photograph on the card, not the card itself. We still use carte de visite, but normally it doesn't have much of a picture on it. However, it's still nearly 6x9 (51mm x 89mm), and is so ubiquitous that it's no longer a craze. 500 for $8.50.
