| What a clever idea,
glow-in-the-dark buttons! Easy to find when the lights are dim and you are
in a hurry! Just kidding. Judging from the construction, it looks
like they were intended to be purely decorative. As you might expect, the
radioactive material is radium-226. The assigned date of the 1930s is pure
speculation.
