I read this today
in 🔗 Austin Kleon’s Newsletter.
Now let me be clear - I am not so old that I ever used one, BUT
I do know what it is and where it was used … and sadly I am old enough to have had a boss who did have such a thing on his desk.
I just looked up Austin on Wikipedia - we aren’t that many years apart … FTW.
LATER THOUGHT - In my younger years I was in the U.K. and Austin will have been in the U.S.A. (Clutching at Straws?)
