Black lined page borders made by computer, no computers in 1961
What black-lined page borders?
Do you mean the boxes in which the handwritten information is?
How did they print crossword puzzles in 1961?
There are plenty of lined boxes on papers from a print shop. Especially since a typewriter wasn’t even being used on this certificate, it is handwriting. You think someone put all that stuff on it and then wrote on it? Or more than likely had a box of blank certificates and wrote on it?
Were you around in the era where you ordered blank “forms” from printshops and filled them in? This wasn’t 1861, this was 1961. We did have SOME technology that was around before computers.
