Trying to identify Cobalt Stone with "ER" letters found on shore of Lake Michigan

This piece of cobalt/navy sea glass was found on the shore of Lake Michigan, Near Winnetka, IL.


It has the letters "ER" on it and appears to be somewhere between cobalt and navy blue in color.

Any ideas of what the source was for this glass?

Thanks!

Cobalt "ER" possibility
by: Victoria

Probably Bromo Seltzer; made in Baltimore and packaged in a cobalt blue jar about 6 inches high high, round with a lip designed for a stopper not a cap. Nationally distributed.

Unfrosted version clear blue with high lumination. Widely imitated today


Full details can be found on the web.Search Bromo Seltzer and you will find the original building which has now been converted, I believe, to apartments.

You may find a close up of their bottle and be able to identify the font.

I'm going with the obvious here, but a Bromo Seltzer bottle?

I grew up in Baltimore, as did Bromo Seltzer :) In the 60's they still had a huge blue bottle mounted on top of their downtown Baltimore HQ.

Google it and see if the font matches? I imagine there were different fonts over the years though.

Did you see the link to this post on facebook? My sister found the SELTZ part of this glass 45 minutes to the north, in Kenosha, WI, on Lake Michigan! So cool!She posted a picture of it on Sea Glass Odyssey facebook post.

I'm pretty certain it is part of a Bromo-Seltzer bottle. Thry are that type of cobalt blue and the ones I have all have the long space between the ER. Emerson Drug Company made the product.
