The Goops books, originally published between 1900 and 1950, were created by the artist, art critic, poet, author and humorist Gelett Burgess. The characters debuted, conceptually, in the illustrations of Burgess' publication The Lark, in the late 19th century. The Goops also appeared in panels in the popular monthly children's publication St. Nicholas, as early as 1898. The Goops series is among his most famous works. They appeared as a group of balloons that were used in the 1930 Macy's Thanksgiving Day Parade.
