How do you like this gentleman? He’s from the Met’s online collection of fashion plates, in Men’s Wear 1790-1829, Plate 032.
I know a gentleman with a similar waistcoat and a similar smirk who needs only the umbrella and spy glass to complete this picture.
In case you’re wondering, the Hull Museum (UK) has a page devoted to a brief history of the umbrella. While classically and stereotypically British, it certainly rains enough here to justify carrying one. The British Museum has 46 trade cards that include umbrellas, with a few pre-1800 examples.
