Celtic knotwork tattoo design of a single wild boar showing its life cycle nested inside itself. At the core a baby boar with no tusks, inside it an adolescent boar with small tusks, and the outermost form a full-grown adult boar with large curved tusks. All three stages share the same outline and flow, layered like nesting dolls, unified as one creature, black ink Celtic knotwork style.
