Sales from a commemorative liquor bottle featuring an image of New Hampshire’s Old Man of the Mountain have generated more than $66,000 to help preserve the Hall of Flags in the State House. The New Hampshire Liquor Commission started a campaign in December to support preservation of the 115 historic flags. Nearly 80 percent of the 9,000 bottles sold by March. Fewer than 1,600 remain and are available at New Hampshire Liquor & Wine Outlets for $29.99. The Hall of Flags features a series of wartime flags, including 88 Civil War flags, as well as flags from World Wars I and II and the Vietnam War.
