Laboratory research, anyone? Here's a Bakelite button that looks like a scientific experiment with its green mass floating in what resembles a Petri dish. The section surrounding the green spot is apple juice in color, but there's a greenish tinge to it as if the green spot is being reflected. Studying this button, I'm reminded of undrinkable pond water that's rife with pollywog pee and who-knows-what. Anyway, don't we all love a button that smacks of infectious bog scum?
