Picked up this lovely small vase on Australian Ebay with an irridescent spiral which is extremely well done. Sorry about the signature I did not realise my handheld shot showed so much shake.
I suspect he may be Ameerican or Canadian - but can't get a good line on him via Google. One other piece on 'Ioffer' dated 1984 shows the same signature. It is an USA site so that is why I suspect Bowlby may be American.
