Lee is also including his take on each game's box art with orders of the related pieces, but it's not just prints that are up for grabs here - Lee is including "a bunch of loose stickers and a single unopened pack" of Merlin brand stickers from 1989 in each order. He's also throwing vintage enamel pins into random orders, so make sure to practice whichever luck ritual you follow before clicking the order button. Both the stickers and pins are available while supplies last, so if you order late and don't recieve stickers, everyone else beat you to it.
Grabbing your favorite piece from the Mario Madness series will cost $25, or you can cave and get one of each series for $100.
Update: Lee has reached out to explain the relation of the Merlin brand to the stickers he's including in orders while supplies last. The post has been updated accordingly.
