Our method of duplicating things has changed a number of times in the last 40 years. For our every day world of paper, duplicating machines such as Gestetner machines were the economical copiers we first saw in the school office along with the carbon paper copier - known as spirit duplicators. I haven't seen carbon paper for decades. It is still produced and used today for things like copying patterns onto fabric.
I don't remember the beginning of photocopying. They came into use in 1959. My experience was during University, copying textbook sections or literary articles.
I do remember word processing. We were able to use word processing programs on the IBM and DEC mainframe computers in the late 1970s. And then in the early 1980s as I worked on my MBA, we were able to produce our thesis on an early personal computer.
So we've experienced some distinct methods of duplicating words on paper.
Our picture today is a favourite front door in Buffalo in the Summer Street district. I take the same picture each year as I greatly admire the flowers on the door. Our first picture is 2019 and the second one is 2018.
