Portrait of a youth as an artist

The young model is portrayed holding a hand rest tied to a
  stick, essential tools for a painter. The
  painting is part of the series of "heads of character", but also of
  the series of portraits with "extravagant costumes" that used a
  blue-red combination and were very dear to the artist. The strange cap worn by the youth recurs several times
  in the portraits, often ironic, of Fra ’Galgario, declined in various ways.
