From the forward:
What are Bottom Collectors? Perhaps this may be best explained by stating a goal set for working out a version of Roy Walton's "Collectors". The goal was to achieve a clean spreading of the Collectors packet. The means adopted was the addition of three aces plus the three selections to the face of one ace. This is easily done if the six-card stock is on the bottom of the deck. It can be added directly to the face of the supposed ace packet. Thus the name "Bottom Collectors". Another factor that came into developing this approach was that all of the published versions of the "Collectors" I had read had the sandwiching action taking place on top of the deck. So I asked: "Why not at the bottom?"
