I purchased a painting (print on canvas) by the artist Norman Rockwell from Hidden Treasures Thrift Store (2915 Pentagon Dr, Saint Anthony, MN) on 04/30/2022.
The painting depicts a boy pouring medicine into a spoon for his sick dog. Titled ‘Boy and Dog Caught Cold.’

Purchase price: $3.99

I painted a yellow rubber duck on the painting and then returned this “new” artwork back to the same thrift store of purchase on 05/09/2022, around 6pm CT.
A successful collaboration! Thanks Norm for your contribution to the work.
