Described as "the single greatest rival of Tenniel," Walt Disney created an influential representation of Alice in his 1951 film adaptation, which helped to mould the image of Alice within pop culture. Although Alice had previously been depicted as a blonde in a blue dress in an unauthorised American edition of the two "Alice" books published by Thomas Crowell (1893), possibly for the first time, Disney's portrayal has been the most influential in solidifying the popular image of Alice as such. Disney's version of Alice has its visual basis in Mary Blair's concept drawings and Tenniel's illustrations. While the film was not successful during its original run, it later became popular with college students, who interpreted the film as a drug-drenched narrative. In 1974, "Alice in Wonderland" was re-released in the United States, with advertisements playing off this association. The drug association persists as an "unofficial" interpretation, despite the film's status as family-friendly entertainment.
