Ten full-color pop-up illustrations introduce Filippo Brunelleschi, the sculptor, engineer, and architect who developed the theory of perspective and designed and built the Cathedral of Florence. The details of Florentine life are given as the book follows Brunelleschi's career from apprentice to leading architect. ~ Please see the photos for examples of the pop-up pages. Besides pop-ups there are many flaps opening up more information. The book has firm binding and is clean. There are no markings. The covers bow out a little on on the ends due to the pop-ups.
