Creamer and Sugar Bowl possibly by Vicke Lindstrand

It's very delicate and very small, only 6.5 cm high. It was sold to me as being designed by Vicke Lindstrand, but I don't have a proof for it. There is no signature. Does anybody know it?

Update from February 25th 2013

I found the same pair of creamer and bowl on Tradera with Kosta-Stickers (look at the screenshot). This is a good sign! They are attributed to Monica Bratt in this offer, which is nonsense, because she worked at Reijmyre's. But it's possible that they were dsigned by Vicke Lindstrand.
