Deletion of Carl Busse (architect)

Comment: we should generally keep subjects that have their own German Wikipedia article as de.wp have more stringent notability guidelines than us. In this case however I have failed to see that |our notability guidelines are met based on the online sources in that article, and I cannot find any myself. He may qualify for some subset of |CREATIVE by virtue of https://architekturmuseum.ub.tu-berlin.de/index.php?set=1&p=58&D1=Busse&D2=Carl this but I haven't seen anything that would quite satisfy all standards of GNG. de:Carl Busse (Baumeister)'s (haven't be able link interwiki links of late weirdly enough) sources no. 3 and 4 I'm going to |AGF on as I think GNG would be met with those given what they are referencing and de.wp's stringent standards. The source in our article based on it being a widespreading Berlin travel book (without a preview, better than what the German-language book provides but not enough) and what it is referencing looks like it may fall just below the bar of significant coverage but I think that should be |applied less stringently because of the wide scope of the book. TL;DR: I am willing to assume that two out of three sources contain enough to be construed as GNG-applicable
Stance: keep
