I have a special toy from 1988; It is not very old. However, I can find no records of it even existing! It is a toy produced by Largo Toys Ltd. and was possibly commissioned by Nintendo Power in the first year of the magazines startup. Neither any toy catalogs nor even Nintendo Power have any record of it (that I can find). I found this in grandparent's garage. The game it was based off of was The (original) Legend of Zelda, released in the U.S. in 1987, a year before this toy's production.
This is a small mug (2 1/2 to 3 inches in diameter, 3 1/2 inches tall) that is marked on the bottom, "Derby Silver Co. Derby CT Quadruple Plate" and the number 25. (See photos) It has a small dent in the rim and is tarnished but in otherwise good conditon, to my untrained eye. It was one of the items I received when my parents died and their home was emptied. I know nothing else about it.
