Paris: G. Lèbre (1903). 20pp.
Uncommon production by the arch-esthete of the decadent era, with poems for each month, along with numerous illustrations of bats by Antonio de la Gandara. Bats had become the author's leitmotif and were incorporated into many of his artworks and collectibles.
Very good in stiff wrappers, bookplate of Robert Bernard inside front cover, inscribed by Montesquiou on front free endpaper, one signature loose.
