Semi-serious questions about reenactment

[M. Demetrius]

To cover tattoos, there is a stage makeup that could be applied, various shades to match skin color, or you could simply put a bandage over it, and add some "blood", as if it were a recent battle (or taberna) wound. I know that bandages would not work for some tattoos, because of their locations. But somehow, seeing Charlie Brown on someone's calf just doesn't seem Roman to me. Call me judgmental if you wish.
