Weihnachten in den Bergen

I picked up this 1978 children's book last summer and put it aside for closer to Christmas, which is now! The book is not in English, so I had no idea what it was called, but I really loved the cover artwork. A quick Google search and I found out that Weihnachten is the German observance of what is commonly known in English as Christmas Day. I love that the front cover shows six children in a horse drawn sleigh on their way to some really fun Weihnachten type event, and then on the back cover, we see them on their way back home a little while latter. We know that just an hour or so has passed by the movement of the moon across the sky.
