False work offered: 'signed by Constant'

False work offered as 'signed by Constant', 2014


Recently we came across several murky works that were offered as art works by Constant at an online auction. We got notified and quickly discovered that one of the works was a copy of an existing watercolor, which makes the work an infringement on copyrights. The second was not even close to any of Constant's works, which makes the work either a misattribution or a forgery. And the last was also a copy of an existing drawing.

More and more artists want to infuence the world. They want to show their idealism and improve the world. But their work does not have the impact they envision.
