... on the bottom it has 'made in Bohemia', ...
It also seems to have some letters below the word "Bohemia" - can you check that please.
... which may date it more accurately than just late Victorian. ...
See my comments below.
I'm wondering if it would have come into this country as blanks with just the enamel white dots and then the acid etching(I think)being done here and sent to whoever wanted to sell some souvenirs?
The enamel dots are covering parts of the the "etching".
As for date - I find most of this type of decor hard to determine for age and I have no clear understanding of whether such a piece would be "Victorian" or "later 20th century" (regardless of it being marked "Bohemain".
My reasons :
a) colour of the glass looks to be cranberry rather than older "ruby-ish"
b) the "etched" motifs are quite naive - in the sense that they are more symbolic of older versions. Note that what some folk refer to as a "C scroll" is, I believe, a very basic interpretation of the acanthus leaf (which in the height of the "Bohemian era" was well formed and full of detail.
I wouild welcome comments from someone with access to the decent books on "etched Bohemian work" - "m" are you reading this?
