Turquoise cracked earthenware owl lamp

More art nouveau than deco, but not in the options. Probably created by one of the lachenal brothers, but no clearly visible signature. The turquoise owl is superb. H31 cm l11 cm. D12 cm. Works very well. The lampshade is no longer in good condition, see photos. It is slightly torn and discolored. The base is in ribbed painted wood, and the lamp base in brass.
