I didn’t have cave walls to draw on when I was a kid, I used the side of the garage. LOL!
I am an artist now, are you? I paint animal portraits. :)
Me, I’m a graphic designer who has worked mainly in museum/aquarium settings. Lots of large graphic panels and...HUGE WALL MURALS. LOL!
And, when I was little my sister and I drew all over the walls of our basement play area. ;)
