The Impossible Rubik’s Cube

Honestly, when I came across this ad in an early 80s issue of All-Star Squadron, my first thought was a post along the lines of how a fad toy, the Rubik’s Cube, could produce such a niche product as Cube Lube:

But a quick net search led me to discover that you can still buy it and from the official Rubik’s website, no less. Not so niche after all, I suppose.

Then a closer look at the ad made me realise something: the cube the kid is playing with is impossible to solve, not only because it has two yellow centre squares:

but also five white white squares in the middle top, bottom, left and right positions:

It’s possible that this cube has two yellow faces and two white ones – but that would take up four faces and, aside from those colours, we can clearly see blue, green and red squares which means the cube would have seven faces, not six.

My brain hurts
