Commemorative china mug made for the wedding of Prince Charles and Lady Diana Spencer in 1981. This mug features the official engagement photo of the royal pair along with all the symbolic royal crowns, slogans, etc. The bottom is marked in red with"A.L." and there are no other marks but it is bone china. Measures 3 1/8 "in diameter at the top and 2 5/8" at the base; it is 3 1/2" tall. There is gold smudge on the side of the mug near Charles' photo which may indicate that this is a "second" or damaged piece; the price reflects this possibility.
