Beautiful indeed! But it appears that all the L&J sets have all been taken as paar.cz won't let me Koupit a pair.
Meanwhile
this Guardian article gives us a clue about the true identity of the creatures on the glasses...
"Hanging from the curved ceiling of the old town hall in Brno in the Czech Republic, is the preserved body of a dragon. The beast was said to have terrorised the inhabitants of the city centuries ago, until it was poisoned by a brave butcher. This area of the country is synonymous with myths and monsters. Ivan Mládek’s popular song Jožin z bažin tells of a swamp creature from Moravia – the lush region of which Brno is the largest city – travelling to nearby Prague to eat its tourists. But that was just a song, and the monster hanging by chains in the town hall is actually a crocodile – probably a gift from a visiting king in the 17th century. The myths and legends, however, live on."
You wouldn't believe how well know the song "Jožin z bažin" is,
translated it means "Joey from swamps". The kind of thing you're
gonna meet a lot if your irl name is Joseph/Joe, like in my case.
