Hi
You could have a number of images;
Quills
Ink pots
Fountain pen
Scrolls
Ticker tape
Books
In press
It really depends on what is significant to you – literature is made up of 3 things;
The tools to write it (as above).
The inspiration to think it up.
The courage to write it down.
You could even have a lions head done with 4 quills shaping outwards on the forehead representing courage and the ability to write it down.
Take Care
Matthew
