A. A. Stewart, Type Cases and Composing-room Furniture
“ The early type cases are shown in pictures of the time as made of a single tray containing all the characters of the font and resting in a slanting position on a rude frame or “horse,” at which the compositor is usually seated. All the boxes of the case are represented as of the same size, which probably was not the fact even in early practice any more than it is today. Early designers and artists no doubt overlooked or ignored what they considered an unimportant detail, just as today they often persist in misrepresenting the true outline of the printer's lower-case. ”
