Still waiting for my golden unicorn but there are already some members from GER/AUT who received them.
First impressions are looking cool, want to share it with you.
Here is a

This one was a bought one and it looks like the packaging of the stamp varies to the one which was raffled out.
Following pictures are taken by someone who was a winner of a raffle!

Quiet different imo.. the one from the official onlineshop from post.at looks much better / more valuable.
And finally a photo of the stamp itself:
