Pinner says: "I LOVE SIRKKA KÖNONENS DESIGNS !" The link doesn't provide any more information so I don't know if this is a one-of-a-kind art gallery piece, or a pattern, or retail, but it sure is gorgeous.
Interesting set-up for socks. You do the top of the foot first, then a short row toe, and finally you work the bottom of the sock in stockinette picking up stitches along the edges. Free pattern on ravelry
