To answer your query about a connection between the three vases on page 15 of the
Art Deco to Post Modernism catalogue Paul. There is no connection. I'm guessing that when Jeanette took the photos she felt that the three worked well together as an image, as well as falling into a timeline. This often happens in books and we can spend hours ponding only to realise it's what material that was available at the time which dictates these things

No pressure here then? Wipes brow anxiously....and explains.....in an increasingly dry voice, err, err, well, hmm, ah, yes, well I think that, that hmm, yes, that the vase shows stylistic similarities with the work of JL rather than that of LK.
Of course failing catalogue entries that can be used to verify this, it's still only, perhaps, an informed hunch...............

Cheers, Nigel
