Woolly Mammoth is a delightfully creepy, or perhaps creepily delightful, curiosity shop in the heart of Chicago. Need a housewarming gift for the Addams Family? This macabre little store is packed to the ceilings with bizarre goodies. Two-headed calf? Check. Squishy sea things in jars? Check. Old photos and postcards? Check. Vintage bottles from scary tinctures? Check. Bizarre and unique.
