This birthday card fairly commands you to have a good birthday. The front says "Listen Up Dude" and then inside it has "Have a Totally Happenin' Birthday!" with some random itallics. The front has that famous (as a poster etc) Sonic 1, finger waving art with tiny Eggman in the distance, while the interior of the card is printed with a grayscale screen shot of Green Hill Zone, complete with score in the corner. It's not that common to find a card with a totally printed interior, so this is interesting to see.
