An artichoke and an elevator. A Checker taxicab and a conductor’s baton. A MetroCard and a mastodon tusk.Inspired by “A History of the World in 100 Objects,” the British Museum’s BBC radio series and book, we recruited historians and museum curators to identify 50 objects that could embody the narrative of New York. (Recalling that adage about great minds: In March, Leonard Lopate asked his WNYC radio listeners to participate in a similar project .)The “History of the World” was limited to objects in the British Museum’s collection. Like that list, ours “can only be a history” and “not the history.” And because it is a people’s history, we are inviting participation. Tell us what objects represent New York City to you in the comments section
