A classic old find, this is a red, white, and blue rectangle Ex-Lax thermometer sign. Featured in blue text against a white field, the top banner reads “Ex-Lax” and the slogan, “The chocolate laxative.” The old-style mercury thermometer is positioned below that. The bottom slogan reads, “Millions prefer.”
