From the world of Li’l Abner, I’d put General Jubilation T. Cornpone on a bill. He was a fictional southern general of the American Civil War, “as strong as an ox and almost as bright,” without whose incompetence the South might have won the war between the states!
If it were up to all the banks, cash would be consigned to history so no need for faces on an obselete currency.
If money was totally digital, there'd be no cash to hide under floorboard, and, the state would know exactly what you were worth.
Cash still rules for me.
