Yale University Art Gallery recently closed an exhibition offering a rare opportunity to explore the process of fine-art conservation. "Time Will Tell: Ethics and Choices in Conservation" exhibits the techniques used and dilemmas faced by conservators and their process of preserving and restoring historic works of art.

The artwork ranges from ancient Roman statues to instruments to twentieth century portraiture. The collection includes a portrait of Marcel Duchamp made of highly perishable cellulose nitrate plastic. These objects and artworks are all tied together by similar conservation questions and problems introducing museum goers to a new way of looking at art.
