The picture is of a quilt made by my mother. She explains that it is “a copy (interpretation / based on) an illustration by William T. Cooper from Visions of a Rainforest by Stanley Breeden, I suspect you need to attribute it to him.”
So there’s the attribution. I like it… and it shows she’s pretty talented, too; it’s hard to imagine that that is a quilt, from the picture. Pretty cool.
