Vertigo - Art Gallery and The Portrait Of Carlotta
Then ... Madeleine leads Scottie across town to the art gallery at the Palace of the Legion of Honor (map). This grand edifice, at the top of Lincoln Park, was a gift to the city from Alma de Bretteville Spreckels and was completed in 1924. (Trivia note - Alma lived in the Spreckels Mansion, site of one of the murders in the movie The Sniper). The Palace is a 3/4 scale model of the Palais de la Legion d'Honneur in Paris.
... and Now, just the same.
Then ... Scottie finds Madeleine gazing at a portrait in Gallery 6 of the museum. He calls over an attendant who tells him it's a portrait of Carlotta Valdes.
... and Now
He sneaks up behind her to get a closer look. Not surprisingly the portrait of Carlotta is not on display in the gallery but the two paintings behind Scottie (below) are periodically hung in the adjacent Gallery 7. They are 'Portrait of a Gentleman' by Nicolas de Largilliere' and 'Allegories of the Arts: Architecture' by Charles-Andre van Loo.
Then ... Madeleine is transfixed by the image of Carlotta. The portrait was painted for the movie by studio artist John Ferren but has since been lost.
... and Now, taken from the same spot in Gallery 6.
Scottie realizes that Madeleine's bouquet is the same as Carlotta's in the painting and that her hair is worn in the same style. Spooky.
