and is flammable. A pair of young animators discovered the film in 1947 and preserved what they could. In many cases only fragments could be saved, if anything at all. Of all of McCay's films, Gertie is the best preserved. Mendelsohn and Brotherton tried fruitlessly to find an institution to store McCay's films until the Canadian film conservatory the Cinémathèque québécoise approached them in 1967 on the occasion of that year's World Animation Film Exposition in Montreal. The Cinémathèque québécoise has since curated McCay's films. Of the surviving drawings, fifteen have been determined not to appear in extant copies of the film. They appear to come from a single sequence, likely at the close of the film, and have Gertie showing her head from the audience's right and giving a bow. McCay's son Robert unsuccessfully attempted to revive Gertie with a comic strip called Dino. He and Disney animator Richard Huemer recreated the original vaudeville performance for the Disneyland television program in 1955; this was the first exposure the film had for that generation. Walt Disney expressed to the younger McCay his feeling of debt, and gestured to the Disney studios saying, "Bob, all this should be your father's." An ice cream shop in the shape of Gertie sits by Echo Lake in Disney's Hollywood Studios in Walt Disney World. New York Times film critic Richard Eder, on seeing a retrospective of McCay's animation at the Whitney Museum of American Art in 1975, wrote of Gertie that "Disney ... struggled mightily to recapture" the qualities in McCay's animation, but that "Disney's magic, though sometimes scary, was always contained; McCay's approached necromancy". Eder compared McCay's artistic vision to that of poet William Blake, saying "it was too strange and personal to be generalized or to have any children". Gertie has been written about in hundreds of books and articles. Animation historian Donald Crafton called Gertie "the enduring masterpiece of pre-Disney animation". Brothers Simon and Kim Deitch loosely based their graphic novel The Boulevard of Broken Dreams (2002) on McCay's disillusionment with the animation industry in the 1920s. The story features an aged cartoonist named Winsor Newton, who in his younger years had a Gertie-like stage act featuring a mastodon named Milton. Gertie has been selected for preservation in the US National Film Registry. The first known specimen of the dinosaur Chindesaurus, discovered in Arizona's Petrified Forest National Park in 1985, has
