The postcard is depicting Millbrook Stadium used by the Portsmouth Cobblers of the Ohio State League. The team was in action from 1909-1915, so it dates from that era. Billy Southworth was first depicted on a postcard with the Cobblers. I think its depiction of the industrial/small town feel of the era is great. There is a color version of this postcard, but this B&W one is exceedingly rare. SOLD net to me, postpaid in the U.S.
