This vintage piece is a 1959 Pyrex "Compass" Promotional Divided Casserole Dish (often referred to by collectors as the "Black Star" or "Atomic Compass" pattern). 1Originally released as a Christmas holiday promotional item called the Pyrex Snack Server (Model No. 063), this 1.5-quart white milk glass piece features a mid-century modern black geometric design reminiscent of atomic stars and compass roses.
