Color print advertisement for Ethocel, the brand name for Dow Ethylcellulose marketed for its flexibility and shock resistance under extreme high and low temperatures. The advertisement features an illustration of a metallic sphere colliding with a plastic plate against a snowy background. The plate is held by a gloved hand. A smaller inset illustration shows a railway signal box constructed with Ethocel. The text describes Ethocel as possessing great impact strength and being shock resistance at "zero and far below." Notably, the advertisement was produced during World War II and bears the Company's wartime tagline "Dow: Chemicals Indispensable to Industry and Victory."
