Details: This poster is a sign that reads: Warning. Man Cave. What happens in the man cave stays in the man cave!
A man cave (also sometimes mantuary) is a male sanctuary, such as a specially equipped garage, spare bedroom, media room, den, or basement. These rooms are often decorated by the male, with little-to-no female influence. A man cave is loosely a male-only space to retreat to,[ watch sports matches, or play video games.
This poster is usually printed with a thin white edge border.
