While Art Nouveau in form and decoration (Japanese inspired designs were very much a feature of the style), these vases probably date to the 1930s when Staffordshire potteries were producing affordable items for interior decoration in a range of imitation styles. Compare the Foley ware vases in this sale, Lot 31. There are no direct parallels for the mark on these vases but the type of ware here is very similar to pieces made by the 'Brentleigh' factory, Stoke on Trent, in the 1930s and a similar date and area of manufacture is the most likely.
