You can almost smell the dog urine on the infamous Blue Room couch.
A constant presence in the Manhattan trial of alleged swindling son Anthony Marshall is “People’s Exhibit 9C” — a remarkably detailed scale model of Brooke Astor’s 16th-floor apartment overlooking Park Avenue at 72nd Street.
The tabletop model is so precise, you can almost hear the scuttling claws of Boysie and Girlsie, Astor’s beloved dachshunds, in the dining room — where an allegedly stingy Marshall has been accused of shutting them in, leaving them to urinate on the parquet floor, after he fired the dog walker to save money.
Marshall has been accused in civil actions of practically closing up his Alzheimer’s-stricken mother in the apartment in the years after she broke her hip in 2003.
There with her nurses she stayed — allegedly lying on a dog-urine-stained couch and subsisting on peas and porridge.
Meanwhile, prosecutors charge, Marshall’s lawyers came and went. At one point in 2004, they practically carried the frail and confused woman into her drawing room and strong-armed her into bequeathing him another $60 million, prosecutors charge.
That’s when Marshall himself wasn’t poaching her valuable paintings, prosecutors say.
See the red-lacquered walls of Astor’s terrace-lined library? That’s where her favorite painting, Childe Hassam’s 1917 masterpiece, “Up the Avenue From 34th Street,” had hung over the fireplace until 2002, when Marshall allegedly conned his doddering mom into thinking she was broke — and needed to sell it.
Prosecutors say Marshall didn’t even ask his mom’s permission before hoisting a $300,000 painting by Giovanni Domenico Tiepolo off the wall near another fireplace a year later, leaving only nails behind.
