This is a functional jet pack from the 1994 holiday-dramedy The Santa Clause, starring Tim Allen. These packs were used by the E.L.F.S. (Effective Liberating Flight Squad) towards the end of film as the team is sent to rescue Santa (Tim Allen) from jail! This particular pack was used by E.L.F.S member #2 Ivanka Kotalto, and exhibits Ivanka's name handwritten on the lower backside.
