Portrait of a young man with a dog

The
  signature and date on this painting emerged only after restoration in 1990,
  enabling attribution.
  The
  portrait dates from the artist's early period, documented from 1533, and is
  part of the Venetian tradition of portraiture from the first decades of the
  sixteenth century, both for its style and the composition, and for its
  iconography. The identity of the sitter is still unknown.
