At eye level and from two different directions, the pieces appear as shown. Pieces are only hidden by similar pieces (so behind a pawn, only other pawns can hide). Given that White may mate in one, reconstruct the position.
[Deutsch: In Augenhöhe und aus zwei unterschiedlichen Richtungen erscheinen die Figuren auf dem Brett wie dargestellt, dabei werden Steine nur durch gleichartige vollständig verdeckt. Rekonstruiere die Stellung mit dem Wissen, so dass Wei?#376; in einem Zug mattsetzen kann.]
[NOTE JdH: I removed the coloring of the squares in 14515 and 14516, because I believe they are unnecessary.]
