(I was also looking at Tessenow's music academy in Hellerau (1910 above) which looked pretty lovely. I'm sure it was lovely for him to until everybody for the last hundred years has run around declaring it fascist. Tessenow was infact more communist than fascist, and also tended to shut up in conversation about such things. He was not inclined toward the word.)
The other thing that plagues me about this sketch is that it represents the importance of those aerials above what we might call a nebulous heap of program, and further that I shall be seeing many many sketches just like this but without the aerials from all my students from here on until the summer holidays. I wonder what that means.
