The instruction manual is just a bonus. There is no front or back cover. [Authentic, with markings] Hexagon: 12 Square: 29 Triangle: 19 [Without markings] Large Hexagon: 8 Tire: 2 Total: 70 I was playing with a mix of authentic and unmarked parts. There are some minor scratches from the children playing with them, but there are no noticeable stains or scratches. I would like to sell these to someone who understands that they are used items. ^_^
