Here are some great Sonic themed birthday cards! Each one has a CG art of Sonic doing something (running, snow boarding, standing with Tails) Two are year-specific (5 & 7) and those special cards come with a plastic pin badge. (seen in upper right corner) So it's like a card with a mini gift! Inside, some have repeats of the art, or mazes. (the maze has a Sonic vs Eggman theme, while collecting rings) There are also character profiles (top right corner) You can see the maze solutions on the card-backs. The one with two pictures is a "spot the differences". The messages are "Have a Super Sonic Birthday, or a variant of "Super # birthday SuperStar" These cards began appearing in 2011/fall. You should be able to find them in ASDA stores.
