This is a German shade made in the 1920s. Typically, the panels consist of faded, punctured paper, so it is great to see an example with complete, bright inserts. The starting price is not unreasonable, although as the seller intimates, the brace that would fit in the slots toward the top is missing. Take that into account when considering whether to place a bid.
