Here's an ad from the mid-fifties for Sheaffer Fineline inkpens. Having been born at the tail end of the fifties, we had ballpoint pens by the time I started using them so I never needed to master the intricacies of one of these old-style pens. My mother had a few and they always fascinated me because I couldn't for the life of me figure out how to get them to work! We still had inkwells by the time I got to school but no ink--nothing to dip the pigtails of the girl sitting in front of you into! Nice cartoony art in this ad. Anybody have an idea who drew it?
