I.P.C Media, or Fleetway, as they named themselves back then (after the street they were based on), created hundreds, if not thousands, of strips over the 40 years they were creating comics. Often, the case for many of these stories was that you had to read the first episode to understand what was happening, or how the character got his super power or something. Some classic, well known examples of such stories are Little and Large Lenny, Barney's Badges and Odd Ball.
Now admittedly, The Bumpkin Billionaires isn't really one of them, because the overall idea for the strip is rather basic - a poor family who become rich and want to get rid of their money (If your more of a Smash! fan, you may recall a similar character calledRonnie Rich, a boy who would inherit a million if he got rid of the money he had, which was illustrated by Gordon Hogg), and each episode is rather clear. Despite this, I dug deep into my collection and pulled out the very comic in question, issue number one of Whoopeefrom 1974. So if you haven't yet read it, or don't feel like rummaging around for for your copy, here is that original first story, with the artwork, if I am not mistaken, coming from the hand of Mike Lacey.
