coming back to the examples such as those in the original links here, there does seem to have been a fairly widespread attitude of wanting to differentiate deliberately these C20 'fleur' (flower) cameo pieces from the more expensive and more hand-wrought cameos.
Richardson (possibly due to their proximity to T/Webb in the early 1930's) made their own quite similar product, and called theirs 'Rich Cameo', although they appear to have quite distinctive features when compared with T/Webb (no idea if Richardson signed theirs).
The point of this waffle is that I've just noticed that Mark West, when speaking of these 'economy' cameos, describes them as 'faux' cameo - so another instance probably of someone going out of their way to separate them from the Woodall & co. higher end cameo wares.
Charles Hajdamach also mentions that E. & L. did some cameo work similar to T/Webb and Richardson, but I'm not aware of having seen any.
Unfortunately, I don't have a single piece - economy or otherwise - they are expensive, and as Sue has commented, most of the 'fleur' pieces don't inspire me...........the decoration looks clumsy and lacks the appearance of fine art.
