Here's a complete set of four (4) BURGER KING 'Marvelous Magical Burger King' Glasses from 1978.  These were offered in Burger King restaurants in 1978 for 29 cents with any menu purchase.  The glasses are 6-1/4 tall, fairly heavy, and (I believe) made by Brockway.  Each one is double sided with a different saying related to burgers, french fries, milk shakes, and onion rings.  These are in excellent condition with good paint, no chips, etc.  There is some fading on the yellowish glass.
