I have never seen this until you posted a link. That building is gorgeous and a shinning example of what is possible with a play system, AKA STECKS. The high roof, the zoo staircase, the 1/2 wood braces, please rerelease 7400 before I die, and every other stecks part.
If only geobra continued on this creative path we could have had today all kinds of parts. Brick walls, 45degree, wider towers, 4x roofs, the endless dream list.......
Thanks for sharing your creativity with the golden era of geobra.
