Sorry for posting this here. I couldn't find a For Sale/Wanted section.
I recently stumbled upon an unopened Rubik's Cube with the original price tag still on it. Apparently it sold for $5.99 in 12/81 at the store 'Two Guys', which was a NY/NJ department store chain that closed in the early 80's. It's in beautiful shape, no dents or anything on the box.
I am interested in selling and thought I'd start here. Just reply if you'd like to see pics or get more info.
