So I'm at the library looking for a text for a class, specifically Plato's rendition of Socrates's famed apology, and I find a book in with other classical era Greek texts entitled something on the order of "Great Works of Plato." I open up to the title page, and what do I see, in cursive and with the medium of graphite penicel, the following inscription:

Plato
 
 

Cool! A signed book of Plato's!!.
