Ditmar Urbach not found online

 I have a plate/bowl that is made by Ditmer Urbach but I haven't found it anywhere online. It has a picture of a rooster in the middle left with dark green, dark blue, yellow and burgundy tail feathers and only yellow and burgundy body color. In the middle right there is a small bird that is black with a burgundy, yellow, and blue crest. Both birds have their tongues sticking out facing each other inward. They are standing on bright green grass. Around the perimeter there is black line that goes all the way around. There is 8 blue, 8-leafed  flowers around the perimeter with burgundy designes in between the flowers. On the back there is Ditmar Urbach with the picture of a star,a circle with a Z in it, then a wing on the right. Under it there is a made in Czechoslovakia. What I would like to know is whether or not this is real and/or part of a set. The price. Thank you and any help would be appreciated.
