This is a reference from a drawing that's not yet done.
So it's perfect to say that least. I would've done references for the others, but I'm not gonna be drawing them really at all, as well as that photo Marx had on the 10th page of the audition. (Because I don't know what's on the photo either... yet)
Also, I know the theme song's cheesy, but that's actually my favorite song, I've listened to it since I was a wittle baby
Just an FYI! Marx's shirt is white underneath the vest.
