Artist Johan Österholm’s Antique Skies process begins with the unsheathing of an X-Acto knife. To the horror of librarians everywhere, he carefully slits out blank or nearly blank sheets of yellowing paper (endpapers, for example) from nineteenth-century astronomy tomes, which he unearths in antiquarian bookshops across Europe and later carefully dissects in his Stockholm studio.

Each copy of "Antique Skies" includes a pair of postcard-sized prints, tucked between its pages, with reproductions of works from Österholm’s After Marville (Whiteouts) series, for which the artist applied gesso to archival prints of photographs of Paris taken between 1862–1878 by Charles Marville, the city’s official photographer.
