OK, I'm fairly certain that I've got all the proof I need - unless someone proves to me otherwise! (e.g. that it's a reproduction/fake):
...another thread on this website:
http://www.glassmessages.com/index.php?topic=55848.50-contains a link to a Google Album showing several pages of text and photos from a catalogue of Václav Zajíc's (exhibited?) works:

"Město" pattern shown in index to photos:
"9/ Miska a talíř, v.č. 3559/140, 210, Libochovice 1976"
[Google Translate: "9/ Bowl and plate, no. 3559/140, 210, Libochovice 1976"]
b/w photo - image #9 showing plate and bowl
"ocenění" [Awards]:
...
"Vynikající výrobek roku 1976: soubor „Město" (talíře, mísy v.č. 3559/140, 210)" [ v.č. = (product number?)]
[Google translate: "Outstanding product of the year 1976: set "Town " (plates, bowls no. 3559/140, 210)" ]
(with apologies to any native Czech speakers for any transcription & translation errors !)
I've overlaid the image of the b/w image over my plate - and there's an exact match in the central pattern area (the 2 plates are different sizes)...
[Mod: Sorry, rummager, but the black & white image and the catalogue it is in are most likely still in copyright. So Board Policy on use of copyright material applies and your montaged image has been removed.]
