This picture appears to show Princess Adelaide of Orleans (first cousin of the new Count of Paris) curtseying and kissing the hand of Princess Beatrice of the Two Sicilies, the mother of the current Bonaparte claimant.
It is the honour given by a younger more junior "royal" to an older more senior "royal".
When the Prince of Piedmont encountered the Dowager Shabanou at the recent Orléans funeral, I'm pretty sure that he didn't stop to ask himself, "Does my father recognise the Qajars or the Pahlavis?" before he kissed the hand of the Shabanou.
