Age of Steam Expansion: Holland / MadagascarExpansion

From BoardGameGeek:

Holland/Madagascar is a set of two Age of Steam expansions. The print run will be 200, and the 150 released at Essen will be numbered. The Holland expansion introduces a new type of hexes: the famous polder. It is not allowed to build in a polder until the mid game, unfortunately yellow cities are surrounded by polders! In Madagascar, one of the poorest countries in the world, players have to bid for the negative actions instead of the positive ones! Madagascar expansion introduces also a new goods display.
