vintage Copeland Spode china tea cups & saucers Buttercup pattern, yellow & brown floral

Set of four cups and saucers, Copeland Spode England, 'Buttercup' pattern with the older backstamp. No chips or cracks to any of these, but they have been used and do have a few discolored spots, not surprising as these are very vintage pieces. I've shown the worst of the spots in the photos.
