Gianfrancesco Penni
Born in Florence to a family of weavers, Penni entered Raphael's workshop very early in his life, and collaborated with him on several works, including the famous Rooms of the Vatican Palace, as well as the frescoes of Villa Farnesina, both in Rome. Heinrich Wölfflin and some other writers credited him with the entire execution of the Raphael Cartoons, with Raphael only creating the initial design, though more recent writers believe Raphael did much of the work himself.
Raphael Tuck &amp; Sons
Raphael Tuck & Sons was a business started by Raphael Tuck and his wife in Bishopsgate in the City of London in October 1866, selling pictures and greeting cards, and eventually selling postcards, which was their most successful line. Their business was one of the best known in the "postcard boom" of the late 1800s and early 1900s. Their contributions left a lasting effect on most of the artistic world. During the Blitz, the company headquarters, Raphael House, was destroyed including the originals for most of their series. The company never fully recovered.
