Hi
I know we’d all want for this to be a genuine piece of art glass, but perhaps you’re actually not looking for the producer, but his customer? This looks like the kind of company logo that would typically adorn trinkets and freebies given out to valued customers, and the glass piece itself could just as well be for cigarettes, pens or something, to put on a manager’s office desk. If so, it can have been produced in large numbers almost anywhere. Any designers out there, to whom the logo seems familiar?
