I purchased a painting (print on board) by the artist Brett James Smith at Savers (4849 Central Avenue NE, Minneapolis, MN). The painting, entitled "Morning Encounter," shows a man throwing a duck decoy from his boat into a lake. Purchase price: $2.99 
I painted a rubber duck on the painting, and then returned this "new" artwork back to the same thrift store on 03/19/2023, around 4:21pm. A successful collaboration!
