There are a few easter eggs (or interesting tidbits if you preffer) found behind the cards. Firstly, we see the Volkswagen logo behind Bumblebee's card, making it an officially licensed Volkswagen product. This is the first time we have ever seen this for the G1 Bumblebee toy and it is most probably due to Volkswagen's partnership this year with Paramount and Hasbro for all things Bumblebee.
Also, behind Outback's card, the instructions have Brawn instead of Outback, which we can tell from the robot face. This was also the case in the G1 instructions and it is funny that Hasbro chose to stay oldschool and include these erronious instructions rather than fix them. It adds to the nostalgia which is the whole point of these releases.
