Unsurprisingly, macaw test images go way back. There is one in this old Kodak test image dataset that is often used in CG tests. https://r0k.us/graphics/kodak/kodim23.html https://r0k.us/graphics/kodak/kodim23.html It seems to have been uploaded in 1999 from an old slide dataset. This seems to be the Photo CD from 1993. I suppose the source goes back earlier. https://www.math.purdue.edu/~lucier/PHOTO_CD/ https://www.math.purdue.edu/~lucier/PHOTO_CD/
