The new LEGO shield isn't that bad. A viking shield could vary quite a lot in size. Viking shields between 24-48 inches were common, and somewhere in between (36") was the most common size. The average viking was around 65-70 inches tall, although they weren't as big-boned as minifigs. When comparing the shield diameter with a minifigs height, it's a pretty good size. However, if it is compared to a minifigs width, it should be 20-25% larger in diameter.
I don't have any pictures but I have hopes some of these Greek-city state standards might be printed.
- Sparta: Λ (Lamda)
- Athens: Glaphx (goddess Athena's symbolic owl)
- Thebes: Heracles' club
- Argos: The Hydra symbol
- Corinth: A Pegasus
- Macedons: The Vergina Sun
- Thessaly: A bull's foot
- Eretria: An eye
- Thespiae: The Crescent of goddess Artemis
