An 80-Year-Old Prank Revealed, Hiding in the Periodic Table

Does anyone know what is being displayed in the background of the picture of Seaborg in the article?

See [1]. It looks like variations of the periodic table but arranged along something other than atomic weight. I suppose if they were still discovering/creating elements, they would align their table differently than one where there have been no changes in years.

It looks like a table of the stable nuclei, the y-axis is the number of protons, the x-axis is the number of neutrons.

Each atom type has it's row with the different isotopes. See:
