Illustration of early hominids fighting a pack of hyenas


I loved this illustration when I was a kid. I still do. It brought me closer to imagining life as a cave man than anything else I read or saw. It still does. The gazelle/ibex's tongue dragging across the dirt is a nice touch. I can't remember where this illustration first appeared but I know one of you do. Maybe one of those Time Life books? Who is the illustrator?
