I did a show called “The Counterfeit Collection “ it was an idea at first to do “bad” portrait style remakes of the classics. My first attempts were laughable, so I started trying to make them look close to the original, then I decided I would paint these with puffy fabric paint.
So I did about 30 of the most famous paintings, and had a show out in Seattle. Sold some of the work.
It was terrific practice as the other commenter mentioned. It was a great study. And it was highly salable work because of its familiarity.
