The pin on the map is centered on the Mail Pouch barn in the photo above. This site configuration and the buildings as shown are clearly shown on Ohio Dept of Transportation aerial photo ODOT # 1692-1-8, dated Apr. 20, 1961. The farm site is now the home of the Breitenbach Wine Cellars. The barn was refurbished and painted and the Mail Pouch sign is now gone. Google maps have street views and interior views of the barn which is now named 'The Winemakers Barn'. There are also photos which show the old wood beams and framing still existing. It is possible, but not confirmed, that the old house on the site was refurbished and incorported into the new large building in the same location. The barn is ID'd as MPB 35-79-12 on the Mail Pouch Barnstormer's website.
