Theodore (Alvin and the Chipmunks) - Kelloggs Rice Krispies mask (1989) - backside

$35.00

In the late 1980s and early 1990s, Kellogg’s partnered with NBC to promote the popular Alvin and the Chipmunks cartoon series with a set of three cut-out masks—Alvin, Simon, and Theodore—printed on the backs of Rice Krispies boxes. These cereal premiums encouraged kids to “collect all three” and bring the mischievous Chipmunks to life at home.

This example features Theodore, the sweet and lovable youngest Chipmunk, known for his round face, innocent nature, and big heart. With his cheerful smile and simple design, Theodore’s mask was especially popular with younger fans.
