I have been looking through the amazing watercolors done during the Great Depression by artists hired by the WPA for the Index of American Design. I knew they'd painted quilts...
and many folk arts.
In the quilt references are paintings of cotton prints
like this one by Elbert Mowry.
Mowry was photographed painting the early quilt.
Here is Ellen Duncan's rendering of a wholecloth quilt on a couch
with a detail of the stripe.
By Catherine Fowler
But then I realized the artists were assigned to paint interesting fabric swatches too. I recognized the fabric in Fowler's painting as a fake patchwork print from about 1875.
Miria Lowry's chintz painting was quite familiar
It's on a bookcover that is on my desk.
Catharine Fowler painted a popular pillar print.
See a post here:
Daniel Fletcher painted a wholecloth quilt of this eagle print
Esther Hansen's Mexican War commemorative
like this piece sold at Skinner Auctions
My favorite may be the yellow stripe with a bolt label
that says Fall River Fast Cottons (?)
Here's the home page of the National Gallery of Art with the images online.
Not to overwhelm you---but there are 18,169 images up there from the Index of American Design.
