Excerpt from the Canadian Encyclopedia:
David Thomson's collection has been eclectic, spanning medieval artifacts, letters, coins, animation cels from How the Grinch Stole Christmas, Edvard Munch, Cy Twombly, Mark Rothko, Patrick Heron, war conflict photography, Joseph Beuys and Pablo Picasso, whose granddaughter he is said to have dated. Thomson is also said to have been behind hiring world-class photojournalists to shoot Thomson Corp.'s annual report.
