My Mom's Kitchen Clock

Ceramic front and face features "Mr. and Mrs. Baker, and their two cats". Wood cabinet supports face and encloses brass works. Small brass tag affixed to cabinet rear has GB (Gustav Becker) in capitals and beneath it GESCHUTZT DEPOSE ( German Registration). The ceramic face has the number 4872 (Model or Serial Number) impressed into it. The brass works have some kind of a logo followed by 218. I would like to find out the date of production and scarcity.
