Horn-book.

A tool for teaching children to read, the horn-book was a leaf of paper printed with the alphabet, the ten numerals, some elements of spelling, and the Lord's Prayer. Horn-books were printed in black-letter type, which in the early modern period was believed to be easier to read. The printed sheet of paper was then protected by a thin plate of translucent horn and mounted on a tablet of wood with a projecting piece for a handle.
