Do you know where the words "uppercase" and "lowercase" came from? Here is something nice: Long before modern printing machines, in order to print a document, the designer had to pick one by one the letters from cases and put them side by side to perform words and phrases. Each case had different font styles, like bold, italic, capital letters, different sizes etc. Usually, the cases with the capital letters were placed on top of others, at the higher cases. This is how the letters got the names "uppercase" and "lowercase". Here is such a machine by Naomie Ross. Watch the following video with the whole procedure.
