A striking current photo of George Banda, who served as a combat medic in Vietnam from November 1969 to December 1970, is part of an exhibit, â??Back in the World: A Portrait Exhibit of Wisconsin Vietnam Veterans,â? that kicks off with a Veterans Day presentation and reception Wednesday at 6 p.m. at the Chazen Museum of Art. The photo exhibit â?? which runs through Jan. 3 at the Chazen, and then will travel around the state â?? itself serves as a kickoff for an ambitious project recognizing Wisconsinâ??s Vietnam veterans, culminating with a weekend-long celebration at Lambeau Field in Green Bay in May.
