This one is maybe a bit of a cheat, because Halle Bros. had more than one location and the hat doesn't have a specific address. But both the original Halle building and the Halle Shaker Square building are on the National Register of historic places. Actress Halle Berry (born Maria Halle Berry) was named after the store.
Hat is a cool indigo blue Milan from the Ecuadorian Panama Hat Company of New York under the Supernatural label. There are a few other examples from this manufacturer around the lounge.
I do like the band on this one...pretty sure it's taking a cue from Frank.
