Two hundred years is a mighty long time. While there’s no blue zone on the planet that can guarantee a couple of centuries’ worth of living, for now, we can only celebrate brand anniversaries and, uh, “democracy.”

After having redesigned Cadbury a few years back, UK agency Bulletproof was tasked with celebrating the candymaker’s milestone anniversary with the “Yours for 200 Years” campaign. Working under the idea that design can spark memories and offer a window into the past, Bulletproof brought back some of Cadbury’s most beloved looks, offering seven limited-edition retro packs from the brand that date back as far as 1915.
