This product is a battlemap-scale encounter map presented in both full color and a very viewable greyscale. The standout feature for this series is the effort the publishers went through to make it usable for virtual tabletops as well as printouts: not only did they include the map as a full-size JPG showing all the tiles together, they also put together a version for Maptools, including the vision blocking layer.
Glass Ships and Icebergs is the least interesting of the three Fantastic Maps I reviewed. It features two small (35') ships made of glass (or ice) at either corner of a section of ocean with ice floes scattered between them. The section of maps that contain the ships has been made narrow so you can easily remove them without losing too much of the ice floe battleground, which is a nice touch, but there's only so much you can do to make a map like this appealing.
