Pan Am Event Calendars ☜ 

Here are two fold-out event calendars from Pan Am Airlines, featuring multiple crosshatch spot illustrations reminiscent of the Einsels' or Alcorn's style. The inner poster-sized content is mostly text with small spot illustrations (and difficult to scan), so I'm sharing them mainly for their interesting cover art and distinctive mid-century color palettes. No designer or illustrator is credited on either piece. Pan Am, 1963 / 1964
