Hello Wesley Meyers,
Thank you very much for scanning and posting these wonderful inserts.
As you are well aware, there has been much discussion here at Playmofriends about what Playmobil is (and isn't).
Even the head of Playmobil's Research and Development Department doesn't think that Playmobil was ever meant to be a "construction toy". Maybe it's the word "construction" that causes some confusion. Because, as you have clearly shown and stated, Playmobil was indeed meant to be a "building system"!
And, as everyone can easily see from the attached picture ... It wasn't just Steck in the 1970s, the original Western houses were also meant to be a "building system"!
Thanks again and all the best,
Richard
