This as an early Nintendo game and there were 60 different models – wide screens, panoramas, multi-screens, to name a few. The most popular G & W was Donkey Kong, introduced in 1982 as part of the multi-screen series. Popeye and Snoopy Tennis were big sellers too. And while the craze ended in the mid-80s, there is still a buoyant trade among collectors. Yours is worth £70 to £150 depending on condition – especially the packaging.
