Seinfeld may have been about nothing, but there was plenty in it... pop cultural references, recurring themes, self-referential jokes, and auxiliary characters. Now you can relive all that silliness in this artwork from Kiersten Essenpreis. There are 99 things about Seinfeld to find in this. If you can't identify them all, there's a reference key.
Update: The artist's website seems to have succumbed to high traffic. You can click the picture here to make it bigger, but I didn't copy the reference key.
Update 2: The original website is back up! For the moment. Keep your fingers crossed. I hope she can sell some posters to cover the bandwidth charges.
