Here’s a better photo of the monogram, I’m also including a link with an article about my grandfather Herman Frank’s brewery. The bottle was originally his!

I’m not sure if this bottle is pre-or post 1900 but it belonged to my grandparents who died in the 30’s! Any help identifying would be greatly appreciated!
