Vintage Gunter-Kerzen candle

I have a Gunter-Kerzen handcarved candle. It is 11inches in height and 5inches wide. It reads "craft has golden ground" (in German) on the front. It has various secenes of workers each labeled in German. (some are legible and some are not as this candle is VERY old) I believe it has a removable insert in the top for candle swapping but it still has the original candle so i am not sure. The candle has been in my family for 40 years and was in Germany. It has extremely detailed carvings and A LOT of color. The candle has been slightly burned and the stuckers on the bottom removed. I cannot find this exact candle anywhere and have been told by past family that it is extremely rare and valuable.
