Class bit of glass artefact Wednesday

Anyone that knows me well enough knows that I have a certain - admittedly mostly ironic - fondness for Greek-Australian kitsch. And this glass is pure Greek-Australian kitsch.

Strangely though, I'm enjoying this artefact on a completely non-ironic level. Aside from the tacky (and mandatory) gold-plating around the rim, I really think this is a rather tasteful and high quality piece of South Melbourne Hellas memorabilia.

I had this image sent to me from South of the Border reader Evan, who got them from a friend. Are these glasses 'official'? What year are they from? I haven't the foggiest idea. If I were to hazard some guesses I would say, 'maybe' and 'late 1970s to 1980s'. I wish I had my own.
