Im looking for info on rosemeade pottery with les kouba art

Tweet

I have a set of 4 steins. They are made by rosemeade and have a pheasant in flight and les kouba's signiture under it. As many times as I search for something close I come up empty. The mugs have a large base and then taper to the top. The base is the typical camel coler and pheasant is a ringneck and in coler. It appears to be on take off. Any info would be much appreciated. kgenader830@hotmail.com
