What confounded me when watching James Whale's The Invisible Man was how the formula ingested wasn't invisible itself. How could simply drinking a concoction turn you invisible? The 1940's The Invisible Woman side-stepped that by having the invisibility process induced by a machine designed by a slightly eccentric professor (John Barrymore). This imaginative Mexican lobby card is for 1958's Invisible Man in Mexico (aka The New Invisible Man), El Hombre Que Logro Ser Invisible.
