Curiouser and Curiouser, Said Alice

I was just noodling around, using Google Lens on the production still of the Louis XVI furniture from 1938's "Marie Antoinette" also seen in 1958's "Gigi," and found this very interesting auction item described as a "Pair of Baltic Neoclassical Giltwood Fauteuils en Cabriolet."

The description:

"Last quarter of the 18th century
The underside of one armchair with scrim fabric painted with identification nos. MGM / XX3690 / 7- A. Height 39 3/4 inches (1.01 m), width 27 inches (68.9 cm), depth 20 inches (50.8 cm).

Provenance:

Originally part of a suite of a settee and six armchairs, the present pair was used by MGM Studios, Hollywood, in the 1938 film Marie Antoinette directed by W.S. Van Dyke, starring Norma Shearer, Tyrone Power and John Barrymore. The suite was used again for the 1958 film Gigi, directed by Vincente Minelli, starring Leslie Caron, Maurice Chevalier, Louis Jourdan, Herminone Gingold and Eva Gabor.

Sold for $1,250

The auction was Oct 19, 2022.

So, "Baltic Neoclassical." Hmmm.

EDITED 20250311: I've emailed antiques appraiser Mark Boultinghouse to see whether he can shed more light on this.
