Something I was investigating with the TF-1 guys on for a month and a bit.
Quoting MAZ below:
In this day and age of vintage Transformers and Diaclone collecting, an age where websites, forums, Facebook, blogs, publications and a strong knowledgeable community have helped expose almost every secret of those venerable toy lines, we don't expect to see anything completely new any more. Maybe the odd Finnish Diaclone packaging variant, a foreign Ceji Joustra release of a favourite with exclusive box artwork or even an Italian GiG pre-Transformer with a mish-mash of Diaclone and Transformers colours or moulding that finally gets confirmed. But to find something completely unheard of and new that nobody knew existed, something that has never been seen by the wider collecting community in approximately 30 years, that is impossible to imagine nowadays, right?
