American history is written on whisky flasks blown in two-piece molds in American glass factories between 1816 and 1860. In size these flasks range from 1/2 pint to 1 quart, and amber, green, aquamarine, emerald, blue, and purple flasks are available. However, the real interest in these flasks is the subject matter molded on them, which includes the portraits of presidents, the American eagle, Masonic emblems, Jenny Lind, Lafayette, and ships, railroads, and other subjects of American life. Some flasks are blown in violin shape and others are house or log-cabin form. The most valuable flasks commemorate events and people in American history. All of the Washington flasks are desirable. Some of them have reverse sides with eagles, others have the Baltimore Monument, and others have a ship or a bust of President Clay, Taylor, or Jackson on the reverse side. The bust of John Quincy Adams is found on one flask that has an eagle on the reverse side. The bust of William H. Harrison is also found on one rare pint flask. However, several flasks with inscriptions such as "Hard Cider" and two flasks in the shape of log cabins are also connected with the Harrison presidential campaign. Another flask in the shape of a house or cabin was the popular Booz bottle made in 1840. The portrait of Zachary Taylor is found on no less than twenty-eight different flasks, and the reverse sides of these flasks carry such Taylor campaign slogans as "Rough and Ready," "A little more Grape Capt. Bragg," the Baltimore Monument, or the bust of Major Ringold. Other flasks have the bust of Benjamin Franklin, and Lafayette's bust is on fourteen different flasks. Several flasks have the bust of Louis Kossuth, and there is also a group with the bust of Jenny Lind. Masonic flasks make up one of the most interesting groups; there are at least forty of them. Other subjects include ships, railroad subjects, Pike's Peak, and even popular songs. Historical flasks usually have the name of the subject molded on the flask and often the name of the glass factory as well. Although many flasks are rare and expensive, there are also a great many attractive and interesting flasks of each type available at a small cost.
