Hi and welcome to the board!
Thanks for uploading your pics dircetly to your thread.
Your Exbor piece is very nice, a pic against a plain white background would be good to see the colours better.
Dimensions would be interesting, too.
There are no valuations given on the board, as they are far too subjective; best way to learn about an approximate value is to watch auctions or search finished auctions of similar pieces.
I would think it is a rather uncommon piece, and the "Exbor Czechoslovakia" stamp usually adds to the interest, as those animals were produced for decades...
