Two 1965 Parker Brothers versions of this game exist, though both are labeled Item 400 and the boxes are identical.
The game box for each version contains:
1 burgundy base board (6.38 inches square, same mold as clear boards)
3 clear upper level boards (6.38 inched square)
20 tokens in each of three colors (red, yellow, light blue)
small rules sheet
Version 1 uses simple posts that have a +-shaped cross-section to support the game-board levels. The plastic post does not flare out at the top and instead of having a shaped post receptacle on each board, there's just a round area that the post fits into.
Annoyingly, the Version 1 levels do not have recesses for the game tokens. If the cat or the toddler taps this board setup at all hard, the game will be over.
Interesting the plastic boards have "Qubic Games" in a corner. Oviously for this edition Parker used molds from the earlier edition by Qubic Games. These same molds later show up in Clipper's Qubic game!
If you compare the image of the game on the boxtop to the actual game inside the box, for this version they will match. The box art for both version shows the first version.
