It is fully marked on the base with the Aynsley stamp. I understand from a fellow E Bayer that the backstamp dates it to 1925. It has a white central panel with a beautiful rose pattern, and three dark blue panels with a gilded butterfly and bird pattern, and a fluted gilded outer edge.
This product would be a great fit for those looking for a visually appealing, high-quality cabinet plate with a classic pattern, reminiscent of an old-fashioned home.
