From New York to London to Stockholm, a wide range of work by artists including Henri Cartier-Bresson, William Kentridge, and Jeff Koons is hitting the auction block this month.

In anticipation of these May sales, with the help of the artnet Price Database, artnet News has compiled a list of five of the most interesting events taking place around the globe this month.

Henri Cartier-Bresson: E171 at Bukowskis Stockholm

Bukowskis presents select works by Cartier-Bresson, taken during his time working at Magnum, a cooperative photo agency that the famed French photographer started with Robert Capa and others. The agency, which turns 70 this year, aimed to use photography in the service of humanity—an initiative that is clearly visible in the small collection of works up for auction.
