Here's a little treat, if you go there. You may have heard of the Rhind mathematical papyrus [1]. It's a papyrus that's more than 3500 years old which has some math exercises on it. It's the oldest that we have discovered.
At this "Treasures" mini-museum you will find a small cuneiform tablet with math exercises that's at least 100 years older than the Rhind mathematical papyrus.
There is a Gutenberg bible there. I would say there are at least 10 items more impressive than the Gutenberg bible; I count this tablet as one of those.
