These are possibilities of how the castle series would've looked if it was introduced before 1978, during the stiff mini-figure era. If anyone wants to contribute to this small project, then e-mail me at RobMan2k4life@aol.com. Requirements for this small project include: Stiff Mini-figures (1975-1977) Green Baseplate (any size) Bricks (red, blue, black, yellow, and white are recommended to do this) Obviously LEGO was better off introducing it in 1978, for there would be little to no play value if it was introduced before that. But boredom did kick in and I thought this would be fun to experiment with.
