Ceramic lamp bases signed Roger Colas

These two lamps were found in a flea market by my parents, a good fifty years ago. The richly hand-decorated ceramic feet are in good condition, however, the caps are very damaged. The lamps were used, but today, my parents are emptying out and getting rid of certain old objects. The feet measure 25 cm high and the diameter of the base is 14 cm. The electrical part has been revised. One of the feet has a crack but no break (photo 10).
