The grand Manhattan apartment that the fashion designer Herbert Kasper called home for more than four decades and filled with an expansive collection of museum-quality artwork and furnishings is being sold by his estate.

Kasper, as he was known, died in March 2020 at age 93 after a long career in the fashion industry. The Kasper brand, now part of Premier Brands Group Holdings, produces affordable women’s sportswear and dresses.

The sprawling co-op residence on the sixth floor of 32 East 64th Street, a.k.a. the Verona, has an asking price of $10 million, according to the listing broker, Meredyth Hull Smith of Sotheby’s International Realty, with monthly maintenance of $14,267.
