Head Of A Man 

Vincent van Gogh's oil painting "Head of a Man" is a striking example of his post-impressionist style. The painting depicts a man in a dark jacket with a pipe in his mouth and swirling, thick brushstrokes create a sense of energy and movement, characteristic of van Gogh's work. Though the identity of the sitter is unknown, this portrait is a testament to van Gogh's ability to capture human expression. The thick brushstrokes and deep shadows create a sense of depth and realism, while the man's pensive expression hints at a story waiting to be told.
