Almost none of these maps have survived, but there were occasionally copies made for foreign princes and dignitaries, and some of them still exist. For example, in the Biblioteca Medicea-Laurenziana in Florence, there is a map believed to be copied from the Padrón Real called the "Salviati Planisphere". This planisphere map was probably given by the Holy Roman Emperor Charles V to Cardinal Giovanni Salviati, the papal nuncio, in 1526. In the archive of the Marchesi Castiglione in Mantua, there is another similar world map, produced about the same time and given by the Emperor to Count Baldassare Castiglione.
