While the style is similar to the Nouveau styles of the 1920`s late Victorian Revival,, the same styles were also reproduced in the 1940`s and 50`s !! No way to tell except in the construction methods and materials as it was originally !! Would that make a difference in the value,,no !! These styles usually run in the $350. to $500. range if in good condition !! Older does not always mean more value !! So just enjoy it !!
Another note,,I had that same little French Provincial coffee table at one time !!
