Huh? I'm well aware of the Northern Upright design. That's basically a plainer variant of the St. George design. The chess set I linked to isn't of that pattern; it's a Staunton, just with thinner stems, although I'll admit the Knight, having a small head atop a long stem, does resemble the Northern Upright or other older designs. But the King and Queen, for example, are clearly of the Staunton pattern.
Stauntons with thin stems were very common in plastic toy chess sets. Here is one of the better examples of such a style:

Yes, I should have noted that he had designed two chess sets for FIDE, the one for the 2013 Candidates, and that different one for the 2013 World Championship.
Leaving aside that expensive set, though, lots of different styles of chess set still based on the Staunton pattern, but not imitations of the original 1849 Staunton Chessmen from Jaques, are in existence.
Here is one random example I encountered, I'm not trying to recommend it, but it seems entirely acceptable to me:

Quad, this design actually predates the Staunton design of 1849. It was purportedly design by Lord Hay circa 1840. Known as the Northern Upright or Edinborough, the sets were manufactured by several different makers, hence the slight variations of in design.
The problem with these, and many other high profile sets, was a tendency to tip over the pieces.
Here's a picture of an original antique set.
