Yes, I thought this might be difficult, as we don't have nearly as much info on the nirvanas as on the regular European, UK and US releases.
So Greece continued to make the same ponies as before the licence expired, or did they create new variants after that (other colours, perhaps other symbols as well)? Very interesting, I really appreciate these snippets of information.
Yes, I suppose that's the only way of finding out, but who still remembers in which year they were given a certain pony? I certainly don't, I can't even remember where we used to buy them, let alone who was with me when I selected them.
I think I selected most (or all) myself, I can't remember being given one as a surprise for Christmas or as a birthday present.
But catalogues would definitely be an insightful source of information, I'll bee keeping my eyes peeled for Greek catalogues in particular then.
I don't have Spanish Flutterbye yet - well, I had one, but I bought her for a friend and liked her so much that I decided to get her for myself as well at some point. She had orange symbols and I think she was NC. Most Spanish ponies I've seen on ebay so far seem to be NC.
