Lustige Fibel
A German children's primer, the Lustige Fibel, published in 1875 by Verlags-Comptoir and illustrated by Theodor Hosemann for young readers learning to read. The pictures here are plain line drawings of Roman-numeral clock faces with hands set at different times, drawn in bold black outline with simple hatched shading on the numerals. A designer could take from them the clean, legible numerals and the economical contrast of thick and thin strokes for clock or timepiece graphics.
