Christmas Train Blotting Paper Advert

My mother was going through some of her things and showed me this bit of ephemera and had to explain it to me. It’s blotting paper from back in the days of fountain pens! We aren’t certain of the age, but it's from Missoula, and the family left Montana in the 1940s. I love the smooth art deco-ish lines of the train.

This was a Christmas advertising give-away from a “Special Agent” for “Massachusetts Protective Companies” I assume that he was some sort of insurance agent?
