There is a Genesis on top of the TV, and look how well it is sculpted! It has the controler depicted realistically beside it too. Even the back of the CRT style tv is detailed. It's a surprising amount of quality put into the toy that you don't generally see on other photos. To see the other views of this, you can go to Fast Food International as this wasn't a USA exlcusive item.
This was part of the Happy Train Promo. You can see the TV in there with all the other items in the photo at left. "In 1994 McDonalds celebrated the 15th anniversary of the Happy Meal by having a set of toys called "The Happy Train". This promotion contained 15 toys from different franchises that had previously been in happy meals. The toys all connected like cars and as you'd guess, they make a train. Characters such as Bugs Bunny, Snoopy, and Little Mermaid all appeared in this train and sure enough so did Sonic the Hedgehog." Sonic related
