Designed for the hands-on enjoyment of children of all ages, the Brussels Toy Museum (Le Musée du Jouet de Bruxelles) is a sprawling collection of 25,000 toys owned by the 77-year-old André Raemdonck, a ceaselessly dedicated collector who has read 1,200 books on the subject in the course of amassing his hoard over 35 years. A tender and cheerful portrait of ageing, obsession and dedication, Sunday, We’ll See shows how a playful spirit can transcend the advancing years.
