A few months ago I purchased on a flea market two vases, and ashtray and something small and round that could be a very small vase in this particular colour. No wear at all at the base, but they looked so ZBS - Klinger in design that I didn't even bother to research them as anything else. My take was that they were ZBS vases, designed by either Klinger or someone following similar designs, but produced fairly recently, and that this colour was one of their more recent additions.
