I have inherited a sacrart wall plague of the madonna holding the child of prague in her left arm 12 inchs in height and in white glaze. Has a v with a stylized bee and also w germany along side it. the number H A 5/1 is encised into it I know it dates from 1960-63 but unsure if its a hummel or otherwise I've had no luck after months of research on gaining information. would appreciate any help.
