With James Grimwood-Taylor, she now shares an interest in writing equipment. Anna joined Cavendish in 2018 as Auction Room Co-ordinator but since stepping into the role of trainee describer, her eyes have been opened to many new dimensions of collecting and we are all waiting to see what will fire her imagination next.
