regret I don't have the Carnival Glass book yet, and know very little about the style - but I have looked as some of the sites showing images of bowls although not seen this one (probably overlooked it). Suspect it will be v. common, but think it may have some age in view of the amount of wear on the foot. Dia. is about 200mm - but no marks that I can see. Grateful if anyone does recognise the pattern and colour, and thanks for looking.
