I remember seeing these as a kid; I believe they came out in 1974... the original Rubik's Cube anyway. That would have been when I was four years old, but later in life, many of my friends started trying to solve them. This was in the same circle as those playing Dungeons & Dragon's as well as listening to the coolest new 80's rock music... good times.

Ironically; I am listening to some new music as I write this reply; some Trance/Synth by Giuseppe Ottaviani. I don't know if you are into that style of music, but if so Listen Here If not at least look him up... good stuff. I don't have a cube or puzzle to share, but did resteem so others could perhaps participate... well done!
