I have a lot of baskets, mostly Victorian, I don't think this one is that old. I actually think it is more likely mid-20th century & maybe
Italian rather than Czech.
There is quite a bit of Italian glass from this era that actually does look somewhat like Victorian glass, some straight repros & others more "inspired by" it rather than direct copies. This includes baskets.
The patterned, leaf-like feet of the basket do copy Victorian styles, but the more organic form of the basket itself, especially that split handle, are much more 20th C. in appearance.
I'll probably be bagged out mercilessly for my suggestion of a possible Italian origin, but that's my gut feeling!
