I finally framed and hung up my Helluva Autograph collection.
Originally I just wanted to get Loona and Stolas, and Millie as well, but I realized you really can't get Millie without getting Moxxie with her since they're the love birds of the show.
I later on got Blitzo, but I really only got Blitzo to complete my collection of the core cast, but to be honest I didn't really like how the picture of Blitzo went with the rest, so I just kept him in my autograph binder.
