This is another piece of glass i have been pondering over for a bit but come up blank, i've acquired this with a set of Habitat glasses that are modern, one still has a label "hand made in Spain" they have no wear at all even though there heavy for their size, however this is slightly different more bubbles slightly off center on the pedestal and 60 years of age wear to the base at least, thus i'm wondering if this is an original piece from the same designer that has got mixed up with these modern ones, i have included a picture of all of them together at the end please don't be cross.
It's 8 inches across the rim, 6 1/2 inches in height and 5 1/2 inches across the base.
