Looking at the eBay page, I did not see a date for this image. Since no one is listed as King, it must be during the Regency, but during Ludwig II's lifetime. That limits it to early 1886, perhaps in March to mark the 65th birthday of Luitpold. The portrait of Ludwig II is present to represent he is the King, but at this point he was confined.
However, I believe this image to be either photo-shopped, or possibly a collage done by hand in pre-computer days. Each of the people in it are clearly from other individual portraits. Duke Carl Theodor's positioning is quite tale tell here, as well as Rupprecht being called Kronprinz even though his father is not yet even Regent, let alone King.
But for identifications - standing L-R:
Pr. Leopold (1846-1930) son of Luitpold
Pss Therese (1850-1925) unm. dau. of Luitpold
Pr. Ludwig, later King Ludwig III (1845-1921)
Carl Theodor, Duke in Bavaria (1839-1909)
Pr. Alfons (1862-1933) son of Pr. Adalbert (+1875) and nephew of Luitpold
Crown Prince Rupprecht (1869-1955)
Pr. Arnulf (1852-1907) son of Luitpold
Pss Gisela (1856-1932) née Adss of Austria, wife of Leopold behind her
Regent Luitpold (1821-1912)
the two unnamed women appear to be the wives of the gentlemen immediately behind them:
Maria Josefa, Dss in Bavaria (1857-1943) née Infanta of Portugal
Pss Louise of Orleans (1869-1952) which adds to my speculation about this being put together much later because she did not marry Alfons until 1891
Pss Elisabeth (1850-1938) wife of Arnulf, née Pss of Liechtenstein (oddly labeled only as Pss of Liechtenstein)
I came across the following portrait on Ebay, and was wondering if anybody can fill me in on the identities of the persons. It seems that there are some missing names.
One source of confusion is the question of whether the "Mrs. Royals" system has applied to titles outside the UK. It's common knowledge, for instance, that the woman born as Baroness Marie-Christine von Reibnitz has always styled herself as "HRH Princess Michael of Kent" -- not "HRH Princess Marie-Christine of Kent". After all, she is not a British princess by birth, like her sister-in-law (HRH Princess Alexandra of Kent). So it's only right that she uses her husband's given name with the Princess title.
My understanding is that Archduchess Maria Theresia of Austria-Este actually styled herself in Bavaria, after marriage, as Princess Ludwig: the reason was to avoid confusion with her unmarried sister-in-law, Princess Theresa.
The wife of Prince Luitpold's youngest son, Prince Arnulf, had an even better reason for styling herself by her husband's name, since her birth name was Theresa, not Maria Theresa. Like the Habsburg archduchesses (the middle son, Prince Leopold, married Gisela of Austria), she was a Wittelsbach by marriage, not birth, as she had been born a princess of Liechtenstein. Given all these facts, she understandably was styled as "HRH Princess Arnulf of Bavaria."
Anyhow, bearing all this in mind, I was wondering if anybody can identify everybody (hope the link works) -- https://www.ebay.com/itm/Prinzregent-Luitpold-Familie-Nachfolger-von-Ludwig-II-Bayern-Buttenfaksimile-9-/370757742230
