All Systems SNAFU

I picked up a set of Lyons Maid cards recently, probably from Zoom or Skyray lollies in the early sixties. It was a random purchase in the hope that it might contain some artwork which could reveal clues as to the development of some toy or other. As it turned out, there were some interesting pics in there, such as the Space Glider, prototype Exoskeleton, Walking Truck and the Pneumatic All Terrain Amphibian.
Our resident specialist Philo Toad wanted a look at the set, so I roughly scanned them and sent them across - unfortunately, I had to sneakily do this in work so the quality of the scan is not great! Hopefully, it will be fairly clear which card back pertains to which card!
