You may recognize from #ThrowbackThursdays past, many of Prospect Park Alliance’s historic materials come from one person: Bob Levine, collector extraordinaire.

His collection spans more than a century of Brooklyn’s Backyard and includes thousands of vintage postcards, photographs, maps and drawings of the park. Here are highlights from the collection, selected by Levine himself.

A 1897 cover of the New York Tribune, depicting the day that the 2nd Naval Battalion hopped onto bicycles to explore Prospect Park. Statues would not decorate the arch at Grand Army Plaza for several more years.
