Lickin' LEON or Rat-Sucker RANDALL is a card from the Old Series 10. It is numbered a.408/b.408.
The card depicts a boy enjoying what seems to be a frozen rat. In the background, you can see a cart that reads "Ice Rat, 23 Flavors."
It may be a riff on how kids enjoy cold treats, such as ice cream and popscicles.
