High Quality Content by WIKIPEDIA articles! 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 began to gain in popularity once again. Aluminum Christmas trees found a secondary market online, often selling for high premiums. The trees have also shown up in museum collections.
