Christopher Brosius creates perfumes that evoke real-life aromas -- and memories. His CB I Hate Perfume Gallery in New York City, has, according to the magazine More Intelligent Life, "the air of an austere cabin. Three hundred miniature laboratory vials populate white shelves. Inside the bottles are accords, the aromatic building-blocks with which one can -- for $125 to upwards of $1,200 -- collaborate with Christopher to construct one's own custom scent. The vials of single notes, which can be had individually for around $25, carry hand-scrawled names like 'Rhubarb Leaf', 'Papaya Seed', 'Celo Tape' and 'Crayon'."

But that won't do for bibliophiles. How about In the Library, which Christopher describes as "First Edition, Russian and Moroccan Leather, Binding Cloth and a hint of Wood Polish". I might ask ask for a customized scent: Pratt Lobby, which would blend the cool, airiness of the grand lobby, with the heady aroma of a hundred just-opened hardbacks.
