This is such a great card from 1935; so great that it needs no words to get the point across. I love how the line went completely off the chart in 1930, and how the stylish man and woman are helping him back up the graph.
It’s also interesting because Christmas cards tend to ignore any current unpleasantness going on in the world. I’ve seen WWII cards, but can you imagine one with a Vietnam or Iraq theme?
