The cover page from H.C. Spencer's 1874 Spencerian Key to Practical Penmanship
One ink-drop on a solitary thought
Hath moved the mind of millions.
Platt R. Spencer, originator of the Spencerian System of Penmanship

In penmanship, if the movements are free and graceful, the lines formed will be symmetrical and beautiful; if the movements are slow and labored, the writing will be heavy and inelegant, or, if the movements are cramped, nervous, and irregular, the lines will be rough and uneven.
Let, then, every one seek to gain a practical knowledge of this art, and as long as he lives will it be to him a source of pleasure, profit, and improvement.
