Otto had bought the manor of the Wahrberg (near Ansbach in the Franconian area) in 1901 and after he died there in 1908 he was burried in the family burial place on the eastern hillside. At this crypt placed over the entrance you can see the wrongly designed coat of arms chiselled in stone. The landlords instructed the stonemason to create a tomb slab with the image they had inherited which explains why we can find the non-heraldic image there.
