Anthony Denney the well-known photographer and interior designer built up a large collection of modern art during the 1950’s and 1960’s. A significant part of the collection - worth several million pounds - was lent to the Dallas Museum of Art in 1970. Following Denney’s sudden death in Spain in April 1990, 23 pictures were removed from Dallas to France by means of letters signed "Anthony Denney". The pictures were hidden, along with others from the collection, and were subsequently transformed into an apparently bona-fide donation to the City of Toulouse, thereby stripping the Denney estate of most of its movable assets. The case suggests that long term loans to reputable institutions may be less safe than we might suppose and that something needs to be done to increase security and prevent art loans from similar attacks in the future. It highlights the professional responsibility of Museums to establish conclusive proof of ownership before donations are accepted and of never taking sides in a dispute over inheritance. Lending to a Museum places the loan in the public domain. Open access to information about all loans provide the best protection for them. A distributed public register of loan collections accessible via the Internet - Denney Net - might provide a cheap and practical means of improving security and would be a fitting way to remember a gifted designer and photographer and the recambolesque story of his art collection.
