This small, intricately-designed book cover from 1784, created by La Veuve Hérissant, is a testament to the burgeoning popularity of hot air balloons in the 18th century. The cover of *Le calendrier de la cour* features a hot air balloon in the center of a gold and red Rococo design. The balloon's image, a symbol of the era's fascination with technological advancements and scientific exploration, is surrounded by swirling, ornate embellishments characteristic of the period. The book itself would have contained the royal calendar for the year, making it an interesting historical object, and the book cover a striking example of bookbinding artistry.
