Mystery wine

Today M won this in a Christmas raffle. We were just celebrating our good fortune on winning a bottle of wine when I decided to Google it.
 
Nowhere on the internet could I find a reference to Pieroth Blue 2004 with a label of roses.
 
Is it a fake?  We have no idea where it came from.
 
Does anyone have any ideas?  Raffles are a good dumping ground for unwanted presents (I know cause I have donated many) so I can only assume that somebody somewhere was given this and decided, well, to donate it to a local good cause.
 

I wonder if there are any wine afficioados out there who can cast some light on this?
