This is a big year for the Periodic Table of the Elements as the world celebrates the 150th anniversary of Dmitri Mendeleev's creation.
We can now lays eyes on a fascinating relic of its history.
The University of St. Andrews in Scotland says it found and restored the world's oldest periodic table chart.
St. Andrews detailed the find on Thursday, though chemist Alan Aitken uncovered the chart among a collection of old chemicals and lab gear in 2014 while cleaning out a storage area in the university's School of Chemistry.
The chart was big and fragile and started to flake when handled.
The university says the chart is similar to a second version of the table Mendeleev produced in 1871.
