Georg Pencz (c.1500-1550) – Nuremberg painter Erhard Schweitzer Part 2

The picture has something of this: people, man, indoors, portrait, facial hair, music, wear, musician, sit, pensive, writer, bald, mustache, intelligence, singer, recreation, popularity, administration.
Perhaps it’s a painting of a man with a beard wearing a black suit and holding a glass in one hand and a cup in the other.
