12 athletes/mascots are featured. im pretty sure there are 4 books of 3 making 12 total; basketball (della/mascot/swimmer), cycling (meares/mascot/susie oniell), surfing (surfer/mascot/canoe dude), soccer (cahill/kerr/mascot). ive never seen any in the same book as regulars or any other combination of athletes.
the errors are both wearing black helmets. pretty sure the incorrect one isnt wearing gloves, while meares is wearing white gloves. im not entirely sure which one is actually wrong , but you can swap incorrect for correct, in-store or through woolies online. there are 2x gold versions aswell (also exchangeable),
either way, i have doubles of the no glove version, if you need? will dig out my doubles and check...i need white gloves.
