New surprise additions to my collection

A friend sent me these two postcards of Prince Jiri and Princess Zdenka Lobkowicz and their first son, Prince Robert.  The couple married on June 16, 2012, at Castle Melnik, the family home.  The Castle is about an hour from Prague.

Prince Jiri is the heir to his twin brother, Anton, Prince Lobkowicz.  (There are four branches to the family, each with its own head.)  Another branch is headed by the American-born and Harvard-educated Prince William.

The princely family has its roots in Bohemia (Czech Republic).
