User blog comment:Miniminette/No Poster for Squigly?/@comment-10558422-20131203153916

That is not Big Band's poster. That is the Steam Community official artwork, and every character has one. :)

You are right that the Main Cast and Marie have posters though, and you can see them in there own section in the Skullgirls art gallery.

The closest thing we have to Squigly's poster is this. It isn't official or by the same people, but was made in likeness to the style. It was promoted by Skullgirls on social media (probably due their partnership with EightySixed).
