Appraisals here are for one matched set or one item per question. The boy and girl pair are porcelain figurals by Royal Dux, which is an Austro-Bohemian factory. The figures are a shepherd and shepherdess. These used to sell for considerably higher a few decades ago, however the market has slumped considerably.
The estimate is for the pair together and based on actual recent past recorded auction sales of comparables. Retail 'asking prices' can be higher and vary.
