Why, you ask, would anyone ever cook a turkey in a brown paper bag? Because Paper Bag Turkey comes out crispy-skinned, golden brown and juicy every time. And there's no basting; put it in the oven and forget it.
This is the way my Mother used to roast turkey.
Remove neck and giblets from cavities. Rinse the turkey and pat dry with paper towels. Stuff, if desired. Thoroughly coat the turkey with butter using your fingers or a paper towel. Season generously. Place the turkey in the paper bag. Seal the bag with staples, paper clips or a needle and thread. (Use 2 bags if 1 is too small.) Place the turkey on a sturdy shallow baking pan. Bake at 325° for about 5 hours. Reduce the cooking time to 4-4 1/2 hours for an unstuffed or smaller turkey.
