This is a real ad from a popular magazine from the 1950s. See how
professional the "doctor" looks? He has white hair at his temples to show he's distinguished. He has a serious expression probably because he has hemorrhoids.
Maybe it's because he's thinking about lung cancer or heart disease.
Now, instead of a cigarette brand-of-choice, it seems as though the doctors all have their own prescription drug-of-choice to slap their face on.
It makes one wonder: what exactly is the next deadly thing that doctors will endorse...?
