I’m not victim to psychoacoustic sounds like fingernails on a blackboard that causes some people to recoil and wrap their lips around their teeth. I am the (seemingly intensely annoying) sort who can merrily use steel to clean glass without flinching.
The screech of file on thin steel is as acutely distressing as fingernails on a blackboard to many individuals as portrayed in this early nineteenth-century cartoon. A dandy, seen waiting in his carriage outside a shop, is tormented by the cacophony created by a peddler in the street filing the teeth of a saw.
[in part] Miseries of Human Life by Isaac Cruikshank, circa 1808.
When sharpening my own saws I would occasionally observe, with some levity, unwary passers-by suddenly shying away from my open door as if they had walked into a particularly malodorous fart.

Where, in the name of all that’s holy, do you find these illustrations – and still find the time to be so very productive?

Dennis, I collect eighteenth- and very early nineteenth-century prints and caricatures and therefore have a keen eye for them.
