I think these were made in Czech. circa the 1930s. Some - like these - feature Oriental, Egyptian Revival and Classical motives. Others were tourists pieces - for places like Paris. Some were good quality and others quite cheaply made. I love the Egyptian Revival ones - nos. 2 and 3 are exclusively Egyptian motives. If you are interested please let me know. Ref: 3143 prices around £55.
