Everything I learned about Vespasian, Titus, and Domitian, I learned from reading the 20-book historical fiction series by Lindsey Davis that started with "The Silver Pigs" and featured Marcus Didius Falco as Vespasian's private investigator/informer.

From my collection, a roman provincial coin of Vespasian (Denomication: Hemidreachm) minted in Caesaria, Cappadocia region. The reverse in Victory holding a wreath and palm frond, a common motif in Roman coinage. Sorry, the reverse is blurry.

I like how in this period the die carvers didn't try to pretty-up the emperers. they went for realism. So coins are often the best reference we have for how these men looked.
