It hasn’t been seen publicly in over 50 years, and it’s one of the National Gallery of Art’s most exciting acquisitions in a very long time.

Vincent van Gogh‘s 1889 masterpiece “Still Life of Oranges and Lemons with Blue Gloves,” part of a major recent bequest from the Mellon family, is being prepped in the Gallery’s conservation lab before it’s put on display as part of a long-planned Van Gogh installation this Sunday. The NGA’s senior paintings conservator Ann Hoenigswald is inpainting minor losses on the work.
