LEXINGTON, Ky. (AP) -- Random pieces of metal art have been showing up in front of a Lexington brewery, puzzling and amusing employees of the business.

West Sixth Brewing worker Sarah Landolt says the sculptures first showed up about a month ago, but nobody knows why or who is putting the artwork out.

The brewery staff says it started with a scrap metal sculpture of a person pointing. That piece was later joined by a second little gift. The latest piece of work now sits out front keeping watch over the front door.

Customer Chris King says the art adds "to the culture" of Lexington.
