Trackmaster Flip Face Gordon, Prototype?

Does anyone know what boxes the flip face Gordon would of been on?

Nearly every TrackMaster (HiT Toy Company) set or destination released in the US. There would be the same recurring graphics on the sides saying, "Start with any set, add another destination, add more engines, coaches, trucks, and cargo". In fact, here's a image of it:
The layout in the bottom image also featured a level crossing that took some time to get made. The UK boxes by Tomy replace this image with the James, Percy, and Toby three car packs.

In the first edition of the 2007 Fun Guide, Flip-Face Gordon can be seen on the front cover at the then yet to be released Knapford Station.
