Vintage from the 1970s "The Friendship pattern contained red and orange solid-colored bowls along with patterned bowls that contained a clorful bird and flower design. When initially released the 3 Pc. Bake, Serve and Store 470 Set and 3 Piece Casserole 480 Set included clear lids with the Friendship design. At some point in later production, probably around 1972, the clear patterned lids were replaced with opal lids that also included the design." Pyrex Passion This is the largest round casserole with the opal lid. It is in very good vintage condition. As you can see by the pictures, the pattern is bright and there are hardly any scratches. There are no chips or cracks in the base or lid. Measurements - 8.5" diameter x 10.75" diameter handle to handle x 4.5" high with lid Capacity - 2.5 Quarts Cross posted
