An aluminum Christmas tree is a type of artificial Christmas tree that was popular in the United States from 1958 until about the mid-1960s. As its name suggests, the tree is made of aluminum, featuring foil needles and illumination from below via a rotating color wheel. The aluminum Christmas tree was used as symbol of the commercialization of Christmas in the highly acclaimed and successful 1965 television special, A Charlie Brown Christmas, which discredited its suitability as holiday decoration. By the mid-2000s aluminum trees found a secondary market online, often selling for high premiums. The trees have also appeared in museum collections.
Aluminum trees have been said to be the first artificial Christmas trees that were not green in color. It is more accurate to say that aluminum Christmas trees were the first nongreen Christmas trees commercially successful on a grand scale. Long before aluminum Christmas trees were commercially available at least by the late 1800s, white "Christmas trees" were made at home by wrapping strips of cotton batting around leafless branches, making what appeared to be snow-laden trees that stayed white in the home. These non-green trees made perfect displays for ornaments and dropped no needles. After Christmas, the cotton was unwrapped and stored with the ornaments for the next year while the branches were burnt or otherwise discarded. Flocked trees, real or artificial, to which flocking was applied became fashionable for the wealthy during the 1930s and have been commercially available since. A 1937 issue of Popular Science advocated spraying aluminum paint using an insect spray gun to coat Christmas trees causing it to appear as if "fashioned of molten silver".
Aluminum Christmas trees were first commercially manufactured sometime around 1955, remained popular into the 1960s, and were manufactured into the 1970s. The trees were first manufactured by Modern Coatings, Inc. of Chicago Between 1959 and 1969, the bulk of aluminum Christmas trees were produced in Manitowoc, Wisconsin, by the Aluminum Specialty Company; in that decade the company produced more than one million aluminum trees. At the time they were produced in Manitowoc the trees, including the company's flagship product the "Evergleam", retailed for $25 and wholesaled for $11.25.
