I've designed labels for vine bottles that come from a little vineyard, located in the picturesque Valley of Lower Vistula. It is called "Winnica Przy Talerzyku" and already has got a logo, so what I did was only labels. I did a little research about this region, which is not only very beautiful but also has an interesting architecture (mennonic).
