News article from 1947 about Julius Nelson – a typewriter artist who wrote several books on the subject. An interesting interview where he gives good advice on typewriter art – or artyping as he liked to call it. He organized a competition every year, and received thousands of entries.
He also worked with “typewriter mystery games”. They were basic instructions such as “type Q four times, press return” which resulted in an image. There is an example in the article. It seems that he wrote books about typing well into the 1980s.
