Three museums on two continents have announced substantial additions to their collections. The largest is at the Detroit Institute of Arts, which has received more than 2,000 modern and contemporary works from the estate of the property developer and collector Gilbert B. Silverman and his wife Lila. The gift ranges across decorative arts, jewellery, performance pieces and time-based media, with a particular emphasis on Fluxus artists of the 1960s and 1970s such as Joseph Beuys, George Maciunas and Yoko Ono.

In the United States, two Joan Jonas works have been acquired jointly by The Gund at Kenyon College in Gambier, Ohio, and the Smithsonian's Hirshhorn Museum and Sculpture Garden in Washington, DC. One is Wind, from 1968, a silent black-and-white film and one of Jonas's earliest collaborations with dancers, showing performers battling strong winds on a snowy beach. The other is Mirror Pieces Installation II, from 1969 and remade in 2014, a multimedia work built around mirrors that reflect both the viewer and a television playing another Jonas film, Nudes with Mirrors, from 1969.

The third acquisition is the most fragile. The Rijksmuseum in Amsterdam has received a seventeenth-century book of around 30 drawings by the Dutch artist Rombout Uylenburgh, who worked around 1580 to around 1627, and his workshop. Uylenburgh was successful in his lifetime but fell into obscurity after his death, and few of his works survive, so the rediscovery of the book adds materially to his known output. It was donated by the Van Eeghen family, which has owned it for more than three centuries, although the connection to Uylenburgh was only made about twenty years ago.

What makes the book unusual is that it survives intact: most drawing books from the period were broken up and sold sheet by sheet, yet this one still holds biblical scenes and informal sketches, its colours remarkably fresh from barely being exposed to light. Together, the three announcements show museums strengthening very different areas: a broad contemporary holding in Detroit, a landmark of early performance and film in Washington and Ohio, and a rare survival of seventeenth-century draughtsmanship in Amsterdam.
