MAD - AND MIGHTY! FAT - AND FLIGHTY! (original poster-all caps)

Overview

Charlotte Lord, a widow in her early forties and owner of Manhattan's smartest modiste shop, is about to marry Guy Barton, a wealthy businessman. But Mexican divorces have been declared illegal, so Guy is still married to Sybil Barton, an unscrupulous gold-digger who left him twelve years earlier. She demands that Guy give her $250,000 for his freedom.- Written by Les Adams
