Tiny laser engraving on LED flash lens... anyone noticed this?

I was playing around with some lenses I acquired tonight and while projecting the LED flash onto a wall (in focus), I noticed that on the projection was a small engraving. It looks like an eagle with spread wings. When I'm projecting it, I'm too far to see it, and with a magnifying lens, it's just too small to see what it is. Anyone noticed this? Also, if anyone has a microscope handy... :)

Very interesting find! I will definitely give this a test when I can find appropriate magnifying glasses!
