I’ve had a lot of business cards over the years. Before 1982 I never had a job that was regularly exposed to the outside world or I worked in a bureaucratic institution (MIT) where I was too low on the totem pole. Therefore no cards. When I worked at Augat only managers got business cards. It was a big deal that required approval from corporate. In more recent years printing business cards has become so easy that I change them at the drop of a hat.
