One would of course hope that it is an artist that has reserved this place for art in the form of a mural, but I’m afraid it is not; at least I don’t think it is (this building is soon to be torn down). I think it is a much more trivial matter, and an old dispute about parking space. You noticed the light, however, and that’s actually my priority report to you… Thanks.
The writing seems to say '[This space] reserved [for me]'?
Must be some artist, planning to do a colourful mural [link] .
