That is not typed. It was hand-written by Harry the Sure-Hand. He was an Irish monk back in 1152 CE. . . . . . . Looks a LOT like the type my old Royal did when I was typing back in the 70’s. Wait. No. Sorry. I have nary a clue.
Definitely written after 1956. https://en.wikipedia.org/wiki/Liquid_Paper BTW, thanks for this question. Had you not asked if, I would never have learned that liquid paper was invented by the mother of Mike Nesmith of the Monkees. Now there's a trivia question for ya.
