I have been collecting vintage Nintendo items for about two decades, and although my collection isn't complete yet, I pretty much know what is out there to look for.
Still every now and then I discover something new. Well, the item shown here cannot really be called 'new' as it is more than forty years old. But it was unknown in collector circles until now.
It is called Panda electric clock (パンダ電気時計).
It was released by Nintendo in 1972, one year after they had introduced a first set of five clocks.
Up until now it was believed that these five clocks released in 1971 were all Nintendo ever made. That is, until this sixth clock popped up recently in an online auction. Time to update the history books!
