Interesting form for a beer. Other than the brewery seamed to have closed in 1865 I'm not familiar.
Here's a brief history of Michael Morath and the brewery, see page 4 of the PDF.

I don't recall seeing more than a handful of shoulder embossed American ales, let alone one in THAT color, in 40 years.
There are NONE from Michigan, that I am aware of.

I figured Doug would've chimed in on this one by now, being that he has pulled every variant of this bottle out of the ground. I dug an amber that was embossed in the middle, Morath & Sons. Newark O I'm wondering if anyone knows of another bottle like the one above, to try and figure out what was peened out of the mold.
