Throughout most of the 1920s, Coca-Cola sat on the sidelines as third-parties made coolers for its products, but in 1928 it hired a sheet-metal manufacturing firm called Glascock Bros. to design and build a cooler that it could sell to retailers. By 1929, the rectangular Glascock cooler, with an iced box above and angled racks for empties below, was ready. Coca-Cola sold 32,000 of them at $12.50 apiece in that introductory year.

Glascock Bros. produced numerous versions of the design. Some were described as “Standard,” others were galvanized for “All Weather” use, a “Portable” model featured three wheels (two large ones up front, plus a small one in the rear for steering), and its boxy “Enclosed Base” version hid the unsightly racks of empties from view.

Coca-Cola collectors look for these Glascock coolers, of course, but some also seek the salesmen samples of them, which were produced by the hundreds. Measuring not much more that a foot in height, these handsome miniatures were carefully painted and even featured tiny racks and even-smaller bottles that fit in them.

Electric coolers followed in 1930, but the first ones were too expensive for most retailers—Glascock’s initial electric cooler cost a whopping $150. But electric cooler were obviously not going to go away. In the 1930s, for example, Westinghouse made both ice and electric coolers, whose trademark red design was the work of Everett Worthington. Westinghouse’s coin-operated Vendo Top coolers added another wrinkle, giving customers access to an ice-cold bottle of Coke for a nickel.

As with the Glascock coolers, Westinghouse produced salesman samples of its machines—due to their diminutive size, these items are sometime more popular with collectors than the real thing, which require a lot of room to store and were subject to a fair amount of wear and tear. Some of the Vendo samples were produced out of die-cut folded paper.

Another cooler-related miniature is the Cooler Savings Bank, which cooler salesmen would give to their retailer customers to encourage them to save for a cooler of their own.

After the war, coolers, even the popular Cavalier models, slowly but steadily gave way to modern vending machines. But in one arena, the picnic, coolers still served a purpose. Most insulated Coca-Cola picnic coolers from the 1940s and ’50s are red, but some are clad in metal while others are wrapped in vinyl to make them more lightweight.
