Winnie-the-Pooh is in our hearts. But he’s also on the road. “Winnie-the-Pooh: Exploring a Classic,” an exhibition that originated at the V&A in 2017, has been traveling since then and now comes to Toronto. Original sketches, manuscripts, letters, photographs, and memorabilia bring viewers close to the eternally touching (and touchingly eternal) characters created by author A. A. Milne and illustrator E. H. Shepard. —L.J.
