You’ve seen those scenic motivational posters on the walls
of offices and boardrooms. Which got me thinking…who
invented them? Do they work? Do cartoons work better?
I’ll have to Google those. In the meantime this was…
…THE FIRST EVER MOTIVATIONAL POSTER!

The FIRST motivational poster ever. Stoneage man has drawn poster on cave wall that shows him chasing a dinosaur that will be his dinner.
