This is a beautiful Gloucester Door.
I wonder why some people hang fish that are not caught in our waters above their doors. Maybe the idea is that a fish is a fish and this is a fish town so any fish will do. Or maybe the person that owns this house has a deep connection to Florida game fishing, hence the hanging of a Mahi Mahi. I dunno, but it’s still a really pretty Gloucester Door regardless of what type of fish is hung above it.
