Earliest Laptop?

     "Thought this might cause a little head scratching," declared David Passell.  His email contained this graphic which resembles someone using the earliest laptop known to man.  Has this been photoshopped, I inquired.  No, the truth is out.  The caption states, "Email from the past?  Not an ancient Greek laptop, but a writing tablet on a vase from 470 BC."
It's from a BBC news article.  Thanks for the smile, David.
