Dutch Periodic Table

A Dutch periodic table formulation, Periodiek Systeem van de Elementen, probably from the mid-nineteen sixties: Element 103 Lr (shown as Lw), discovered 1961, is listed but Rf 104, discovered in 1964 is not shown.

Note how this formulation shows the noble gases, He-Rn, both on the left-side and the right-side.

This historic and original periodic table is listed for sale (Nov. 2015) on the Not On The Hight Street website.
