Monumental Brass (5e Equipment)
From D&D Wiki
Cost: 160 gp
A two-dimensional memorial crafted from sheet brass mounted on a marble base. The figure of an aristocrat, either alone or with their family, is incised in the brass along with heraldry and a motto. Such memorials become popular when there isn't enough space for a full monument or effigy.
