Viticulture: Visit from the Rhine Valley

From BoardGameGeek:

You have new visitors! Visit from the Rhine Valley, an expansion for Viticulture, provides you with a new set of eighty visitor cards, which focus less on victory points and more on the wine business itself. These cards have their own unique backs as they must be played without other visitor cards from Viticulture, Tuscany, and Moor Visitors. -description from the publisher
