WHY WON'T THESE PEOPLE JUST ASK AN EGYPTOLOGIST??We
do exist, after all. We're not mythological creatures. And we're generally cheap hires, since you don't get rich reading ancient texts.
I can't say anything about the cave paintings from professional knowledge, but those hieroglyphs don't say anything, and some of them aren't even real hieroglyphs.

Bah... if the language still languished undeciphered, or no one studied it, or there had just been a devastating plague that had killed all the world's Egyptologists and all of their students... OK, then I could understand this. But, come on, Pelikan! I know grad students who'd happily advise on this sort of thing for small fees. And I like fountain pens; I'd do it for the price of lunch at Subway.
I'll bet the cuneiform and Greek letters don't say anything, either.
The others are nice pens, though.
