The Victorians used to drop off calling cards, and not necessarily stay to visit. If you had someone famous call on you, you would display that card on the top of your stack for everyone to see. I bought some from Victorian Papers when I moved, and also have my email address on them. That’s all you need. Name, address, email, phone. It does save time when someone wants your number or address. Here is the website.
