For your consideration, here is a Vintage Mrs. Anderson's Pie Crust Shield, made of Aluminum.  It has a diameter of 10 3/8 inches.  It has some light wear on it.  Used in baking to keep the pie crust from getting overly cooked.  It will be mailed in a box for protection.  The item pictured is the actual item up for sale and comes from a non-smoking household.  (430.822s-.9bb)
