I've finally nailed it. That yellowish figurine on Wallis, duchess of Windsor table, I finally know what it is: it's called a "Terror dog"; from Ghostbusters the original first movie.

https://ghostbusters.fandom.com/wiki/Temple_of_Gozer

"The Temple of Gozer consisted of a large ancient pyramid, a staircase, translucent doors, two altars for the Terror Dogs (Zuul the Gatekeeper and Vinz Clortho the Keymaster) to wait upon, and assorted obelisks and hieroglyphs. At its summit, there was a bright light. It was seen in Dana Barrett's refrigerator–in Gozer's own dimension–and in the top of Dana's apartment. Also, an engraving of a scene with the Temple portal and statues of its two minions, can be seen at the top of 550 Central Park West.

Once Zuul and Vinz Clortho completed their ritual, a portal opened and Gozer crossed over from the temple onto the physical plane. The Ghostbusters crossed the streams and destroyed the temple (and part of 55 Central Park West). They were later sued by every city, county, and state agency, effectively forced out of business. "

There is more to read in that link. Here is another one about the building. Notice the Obelisk in the b/w photo from the movie.

"Best known as the apartment of Luis Tulley and Dana Barrett - and the point where the evil Zuul enters our dimension - in Ghostbusters, this 19-floor housing cooperative is located in Manhattan, New York City, U.S.A. The building was built in 1929 and designed by the firm Schwartz and Gross. Both the interior and the exterior possess unique architectural features that set the structure apart from its peers. The building is considered a contributing property within the Central Park West Historic District, which is listed on the National Register of Historic Places. (It's also where Walter lives in Elf!) The building is a contributing property to the Central Park West Historic District, which was added to the National Register of Historic Places on November 9, 1982. The property is also a contributing property to the New York City's Upper West Side/Central Park West local historic district. The entire area along Central Park West is considered one of New York City's finest residential neighborhoods. Benjamin Schwarz, writing for the Atlantic Monthly said of the buildings along Central Park West, "no endeavor on earth is more arduous than getting into one of these buildings." He specifically cited the "details of Donna Karan's deal for her digs at 55 Central Park West." The building also holds significance in American popular culture because scenes from the 1984 film Ghostbusters were shot there. In the film, the building is said to have been designed by an insane architect named Ivo Shandor, who started a secret society which performed rituals on the building's roof as early as 1920. The building, however, was not built until 1929. Since the movie used the building in 1984 it has been known as the "Ghostbusters Building," though it was portrayed as much taller and with a different roof in the film. Well known residents of the building have included Calvin Klein, Donna Karan, Ring Lardner, Jr. and Marsha Mason."
