I am embarrassed to say (because I used to work at this place) that IDK what this is: some kind of brush or broom made with corn husks, I guess, although that does not sound very sturdy. Displayed in the kitchen of Magnolia Mound Plantion.
Was it something you could run your boots through to wipe off the mud? I worked in an Early American village one summer during college but I don't remember seeing anything like this there. Sure makes for an interesting photo though! I like the way the light is falling across the corn husks.
