Crystal Absinthe Glasses?

These are - I think- absinthe glasses, but I'm not sure at all. They're made of crystal for as far as I can see/hear, and the shape of them is somewhat like the type of glass depicted on the early 20th century Absinthe Bourgeois posters. They have facets carved in them, as well as three separate measuring lines.
The receptacle part of the glass has a green tinge to it, which is beautiful and somewhat reminiscent of vaseline glass, but makes me think these are not particularly old.

I'd like to know more about these; does anyone know where they come from or who manufactured them, and possibly how old they are? Also, are they absinthe glasses or am I completely wrong there?
