This is Art Nouveau at its best. We don’t know who made this cup and saucer but it could have been Minton, if you look at the shape and the colours. The cup imitates the Georgian ‘bute’ cups from a hundred years earlier, as does the deep saucer that has no well. It must have been made around the year 1900 and would make a perfect Mothers Day present! You can find the listing here in my Vintage shop.
