My small collection. The blue in these glasses is eye-popping.
The piece on the left I think dates to the late 1830s, the piece on the right is cameo glass and dates to c1860.
I'm researching the Fußbecher in the middle at the moment hence the picture is side on so as not to show the detail on it
It has a lot of gilded detail that doesn't show in the group pic, so I've added a pic taken against one of the windows in our house where more of it can be seen. It is also gilded on the foot but not possible to light it to show that as well. Some of the cutting in the glass is reflected in the detail of the window
