Wonderful copy of "The Glass Flowers at Harvard." This book has dozens of pictures of incredibly life-like flowers made of glass by Leopold and Rudolph Blaschka from 1887-1936. It will be hard for you to believe that these works of art aren't really live flowers. And as an added treat, four passes (2 adult, 2 children) are included so that you and your family can visit the fabulous exhibit at the Harvard Museum of Natural History in Boston. And don't worry - if your sons can't bear the thought of looking at hundreds of flowers, there are many exhibits that are sure to capture their interest. Dodos, Trilobotes and Meteorites, Climate Change: Our Global Experiment and the zoological, mineralogical and geological galleries. Plan to spend the day!
