While a lot of OPALINE BROCADE has made it's way to the USA, due to collectors like me, I have never heard of it being exported here from point of manufacture (but it could have happened). Northwood started reproducing this pattern 14 months after JWW first announced the pattern, and Northwood would have been able to sell it cheaper in the US than JWW could have sold it with the cost of a boat ride included. Northwood's shapes are well documented with original catalog illustrations, and this is not a Northwood shape. I also have not heard of any pieces being suspected as Bohemian in origin. I have handled quite a bit of JWW OPALINE BROCADE, and this is consistent with other pieces I have handled. It may have been a decorative flower arranger piece, too.
