The Duke and Duchess of Guise, Queen Amelie of Portugal and the Count and Countess of Paris. I expect this postcard was published at the time of the engagement of the Count of Paris in 1930.
Prince Jean, Duke of Orleans (1874-1940) was married to his first cousin, Princess Isabelle of Orleans (1878-1961). They were the parents of three daughters, Isabelle, Francoise, Anne and Henri, Count of Paris. He married Princess Isabelle of Orleans-Braganza at Palermo on April 8, 1931.
Queen Amelie of Portugal (1865-1951) was the widow of the assassinated King Carlos of Portugal. She was also the elder sister of the Duchess of Guise.
