You're showing your *strange* bit after all! While I was away, I tried reading my "American Studio Glass 1960-1990" (Martha Drexler-Lynn), but sadly, found it highly unhelpful for my needs.
On p.52, there is a black and white pic of a panel of judges (all named and id'd by academic position) studying some pieces of glass from the 1968 Toledo Exhibition.
One of the bits of glass looks very similar to yours. The book omits to tell you who made the glass, of course.
(it seems to be mostly an academic treatise on the acceptance of glass into art, it's not really about the glass or the artists creating the movement at all. :grrr: I found it very dry and unrewarding.)
But perhaps some folk like books from that angle.
Personally, I've read far more interesting academic theses, though they've been scientific rather than art subjects.
