Strange Makers Mark.

[dragonchardra]

I found a Lysol bottle that is clear glass. Not such a rare find. But the makers mark on the bottom is driving me crazy. I don't know what it is or who made the bottle. It looks like an I inside a square. The only thing that came up was an O or C in a square and it doesn't fit either of those descriptions. I hope someone can help me find out who made this bottle and when the company was in business. Thanks!
