M180905a
Oval containing "KERAG", "KARLSBAD" and "CZECHOSLOVAKIA".
These mark variants are mostly found on kitchen canisters or cup-and-saucer sets. If applied, the second "CZECHOSLOVAKIA" is always of the same semi-circle type. This could suggest an original manufacturer, indicating that "KERAG" was merely a distributor or retailer. The addition of the Bindenshild mark was probably used as a low-end marketing ruse, as neither the decoration type nor the style verified its use.
