Architectural toy building block set in wood with paper and mica, made in Germany, c. 1920 vintage antique

Architectural toy building block set in wood with paper and mica made to look like windows, with printed ashlar bricks, arches, turned balustrade, and other architectural forms, made in Germany, c. 1920.  The cover illustrates how the blocks can be used -- a seemingly complete set.  Unusually small and charming.
