I purchased this unframed because I did not want the black frame and mat on the other option and I really wanted another color floating frame for it.  With that said, the art is lovely but the frame isn't 40 inches square.  One left to right measurement was 39 14/16 nd the opposite end was 40 1/8.  The same held true for the up and down measurements on both ends too.  I had to be very careful when buying a frame that would accommodate mismatched dimensions.  It's slightly off but I hope when the frame get's here I can make it work.
