I am not sure about the first one, it is very original and unique, I love it!

The second one looks like a mock prairie point to me :D:D:D

They are two different quilts. I can scan the other side in the morning- looks like the back of the triangles are part of the backing- love it. The other quilt with the black and red triangles look like the folded up squares into triangles, and just stitched the bottom. It does have a lot of wear though around those triangle edges, but I really love them. I love old quilts!!
