In the 1930’s, an American toilet bowl brush manufacturer changed the look of artificial trees.
The artificial tree was made by the Addis Housewares Company, producers of brushes used for cleaning toilets. During World War II, when real trees were hard to come by, Addis made these artificial trees on their brush-making machinery. Many of these fake trees were sent to London where, after the city was bombed, there was no access to real trees for the holidays. Earlier versions of artificial trees used feathers, but these bottle brush trees are more similar to the artificial trees produced today.
