QSL cards are written confirmations of either a two-way radiocommunication between two amateur radio stations or a one-way reception of a signal from an AM radio, FM radio, television or shortwave station. They can also confirm the reception of a two-way radiocommunication by a third party. A typical QSL card is the same size and made from the same material as a typical postcard, and many are sent through the mail as a standard postcard.

Founded in 1766, the Fragonard Museum is one of the oldest museums in France. Honoré Fragonard was one of the first medical masters of France, and his extensive collection contains rooms devoted to anatomy and teratology, articulated animal skeletons, and to disease and pathology. The highlight of this extraordinary museum is by far, however, the écorchés, or “flayed figures” of Honoré Fragonard. These écorchés were carefully dissected animals which were posed and mounted. While many of his contemporaries were creating artificial anatomy models from wax, ceramic and plaster, Fragonard spent years preparing hundreds of these écorchés through a very difficult and, to this day, secret process similar to that of plastination.
