One wintry day in 1983, alongside other street sellers in the East Village, David Hammons peddled snowballs of various sizes. He had neatly laid them out in graduated rows and spent the day acting as obliging salesman. He called the evanescent and unannounced street action 'Bliz-aard Ball Sale', thus inscribing it into a body of work that, from the late 1960s to the present, has used a lexicon of ephemeral actions and self-consciously black materials to comment on the nature of the artwork, the art world, and race in America. And although 'Bliz-aard Ball Sale' has been frequently cited and is increasingly influential, it has long been known only through a mix of eyewitness rumors and a handful of photographs. Its details were as elusive as the artist himself; even its exact date was unrecorded. Like so much of the artist's work, it was conceived, it seems, to slip between our fingers -- to trouble the grasp of the market, as much as of history and knowability.0In this study, Elena Filipovic collects a vast oral history of the ephemeral action, uncovering rare images and documents, and giving us singular insight into an artist who made an art of making himself difficult to find.
