Putting together a promo dish with it's correct accessory is usually fairly easy. There are a couple of instances that can be confusing or which the casual observer might not even notice. At left is 1958's Cinderella Cradled Casserole; on the right is 1959's Bluebird. The dishes actually fit either cradle quite nicely, but they're not the same. Photos can often distort their angles and proportions. The long curved bars of the 023's cradle on the left, however, don't also bend toward each other like those on the oval casserole's. Also, when viewed from the side, Bluebird's cradle's handles are even with or slightly higher than the top of the bars which support the dish.
