Painted in the winter of 1916-17 and purchased by the National Gallery in 1918, The Jack Pine is once again on a European tour. After being part of Painting Canada, Tom Thomson and the Group of Seven, at the Dulwich Picture Gallery in London, UK, this work and others are now on their way to Oslo’s National Museum of Art, Architecture and Design. The exhibition opens in Oslo on Jan 29. Before The Jack Pine left Canada it underwent the most extensive cleaning and restoration in its history. This short, behind the scenes video, takes you through just how that restoration was done.
