Rocky (and Bullwinkle) Kaleidoscope Puzzle (1969)

I am not only a sucker for vintage "Rack Toys," but also vintage Rocky & Bullwinkle stuff, and I just picked this up from Ebay last week.  The back of the card is unfortunately blank, but when I was examining the puzzle, I realized that the shapes looked familiar.  It turns out, they are identical to a larger, wooden version of this puzzle that I have, where the object is to build a 3-dimensional rectangle, SO, this puzzle had two different objectives, which is pretty cool...although, poor Rocky can't seem to figure it out!
