I've seen this blue vase (first picture) described as Skrufs, Lars Hellsten designer, a few times, so it wasn't high on my list to confirm, but recently Dirk cast some reasonable doubt on that by remarking it looked a lot like some pressed Walther vases.
I've actually acquired one of the similar Walthers (second picture, clearly labeled as Walther), so I could compare a bit. While I agree the idea of the blue seems similar, I also see differences. The size and the general shape are different, and the finish is quite different (for instance, while they both have a square rim, the Walther rim is flat, while the blue rim is not. Also, the Walther has pressed lines on the side that are more pronounced and different than the blue, whose press marks are very vague.
However, I think it's a good opportunity to ask for a few that are a bit more at home with Skrufs how well documented the blue is as a Skrufs vase?
I have more detailed photographs of the rim and the base available if anyone thinks that would make it easier.
