From todays POTD All you ever wanted to know about the clothes peg but were afraid to ask. its a full 12 minute read but a small bit of effort and curiosity is always required to acquire knowledge.
Odd trivia link but true, the article includes an image of bit of public art sculpture by Swedish born Claes Oldenburg from May 1974. Clothespin is a weathering steel sculpture by Claes Oldenburg, located at Centre Square, 1500 Market Street, Philadelphia, USA.

After a decent innings, he was 93, Claes has only just this week passed away on 18th July 2022, so a fitting commemoration for his work on the FCF.
One of his installations is called "Bottle O'Notes". Could be another trivia question "Where is the Claes Oldenburg sculpture "Bottle O'Notes" located.
