These are certainly cute little kittens - they date to the 1940s / 1950s and are fully marked with the Plichta of London mark to the base.
Jan Plichta was a Czech who emigrated to England in the early 1900's and set up as an exporter and wholesaler of glass and pottery. He worked from the flat above his small warehouse at 37 Store Street, in Bedford Square, London.
This little salt and pepper set would have originally sat on a little simple ceramic plate stand - however, this seems to have gone missing over the years.
All the same, they are rare items - and in good condition with original cork bungs.
They are so sweet with big blue eyes and painted on eyelashes - each kitty has a blue ribbon as a colour and on the back is a hand-painted thistle - as you might find as a decoration on Scottish Wemyss Pottery.
Each little cat is about 8 cm in height and both cats are in good condition - there is a very faint and slight craquelure to the glaze which seems to be common on Plichta wares of this time - but it can really only be seen on close up and is not stained or disfiguring.
Fair starting price for these harder-to-find pieces of Plichta marked pieces - if complete with their original tray would probably be about £95.
