Anyone know anything about it?
Andy?
That's a new one on me...
I know glow-in-the-dark stuff was around in the 1960s, especially popular in toys, but this is apparently 1950s. Aside from the wraparound label, is there an instruction sheet anywhere? If so, it'll have a printing date code on the bottom, using capital letters. (Maybe the wraparound label will, too; I can't see all of it from here.)
