Regular readers may remember that I'm a huge comic fan, with boxes in the basement filled with rotting printed paper from my formative years. Just cracking open a comic from the late sixties and smelling that unique, musty paper smell fills me with all sorts of nostalgia. It a scent that collectors of comics, baseball cards and other useless but essential paper paraphernalia will know and love, and I've often said that whoever manages to capture it in a bottle would make a fortune.

While this isn't exactly the same thing, it's enough to make me want to gamble $35. A new scent called In the Library from I Hate Perfume is filled with notes of "Russian and Moroccan leather bindings, worn cloth and a hint of wood polish". This I have to have.
