like perhaps many other already well-defined subjects in life, I'd imagine there is virtually no debatable room remaining for 'opinions' on what constitutes art deco - people have been banging on about it for too long for the style to be lacking in definition.......... perhaps misunderstood though.
Rather than referring to a period, it is, apparently more a style than anything else, although we tend to think of it as occurring somewhere between the end of the first WW and c. 1940, and although dangerous to sum up any art movement in anything less than a substantial coffee table book, deco is typified more than anything else by angular geometry in whatever form it occurs.
I love it ..... why I'm not entirely sure.... I think it's the preciseness and streamlining - the balance of shapes and lines........ it's alive and vibrant and pushes boundaries...... and of course the risqué aspect.
I think we'd all doff our hat to you as the expert on the subject of glass from that area Nigel, and there are some to-die-for pieces out there, although usually out of range of our pockets.
As is so often the case with these threads, folk aren't usually very forthcoming with their ideas, unfortunately, but it would be interesting to have an input from countries other than the U.K.
Now, where's Kevin - he must surely move these last few posts.
