It's always a hoot-and-a-half to find deep spec authenticity. For example, I am intrigued by a line in one of the 800 letters Vincent van Gogh wrote to his brother Theo. The year is 1885 and Vincent is being covertly hostile to his little brother. He gives him a dig about what he was wearing in a recent visit to the parent's home in Neunan. Theo was by that time a bigtime art seller for Groupal, the company co-owned by their uncle, also named Vincent van Gogh, but called Cent. It doesn't help that Vincent was a total failure at selling art in his short-lived Groupal employ, attacking customers for their bad taste in art and taunting them to buy something better. Vincent's little brother, Theo, was everything that Vincent was not: smooth, polite and a good salesman.
Here is the line that intrigued me: "I cannot help seeing you in my mind's eye wearing a pince-nez with sunglasses." I'm not familiar with the French language, so I thought that a pince-nez was perhaps a style of suit, but the part that is incredible is that Theo had on sunglasses! I wondered what they looked like, and, of course, gravitated to the Benjamin Franklin style round ones:
Maybe so — but my impression is that you have perhaps, in a sense other than the literal one, acquired dark glasses in what you think and do. Suspicion, for instance."
And if you want to read the entire letter here it is:
