Lovely Period Reproductions

Your paintings arrived here this afternoon in good order. They are as well executed and charming as I had hoped they might be. The authenticity of each piece will make it quite easy to blend them into our Americana decor where they will be at home with antiques and indistinguishable from period pieces. I hope to acquire a few more of them. Thanks very much for these lovely period reproductions. Rob NJ - More Testimonials...

Creating a Theorem Painting by American Folk Artist Nancy Rosier

What Are Theorem Painting?

Theorem painting (meaning painting with the aid of stencils) is considered traditional folk art. It was popular in the 1800s. Theorem painting is most often done on white velvet fabric, which gives the painting a soft, lovely depth. Fruit and floral arrangements are the most popular subjects, but scenes were sometimes done.  Learn More About The Art of Theorem Painting!
