"She knew the ugliness of that room by heart—knew it and hated it."
Valancy's room is such a compendium of obsolete Victorian trends, banished upstairs to a space nobody cared about.
Top left: The very engraving of Queen Louise of Prussia! As a beautiful 17-year-old, Louise of Mecklenburg-Strelitz enchanted the future King Frederick William III of Prussia. By all accounts, Louise was a paradigm of feminine virtues, while also serving as her husband's chief political advisor.
Top right: A sample of yellow floor paint, used to cover and seal pine floors. Linseed oil and ochre paint formed a durable, washable finish. Softwood floors upstairs are not a surprise for a respectable but not wealthy family like Valancy's.
Bottom: 1875 "Moy" burgundy wallpaper; Victorian shell box; Victorian beaded pincushion. Many of us today would probably find these quaint and charming, but from about 1910 into the mid-1970s, they would have been seen as intensely outdated and shoddy.
Here, for contrast, is a light, cheerful, up-to-date 1920s bedroom, courtesy of Armstrong Linoleum. I've seen similar looks promoted as early as 1906.
an old chromo of a puppy sitting on a rainy doorstep. That picture always made Valancy unhappy. That forlorn little dog crouched on the doorstep in the driving rain! Why didn’t some one open the door and let him in?
...is a probable inspiration for that chromo, since this painting was widely reproduced. Note the title, as it's on-theme for Valancy.
