Greetings from upstate New York!
I hope you can help me identify and find a book I had as a child.
I do not know the title or what the cover looked like because my copy was missing the cover. But here are the facts as I remember them:

I was born in 1960, so this book had to be late 50’s early – mid 60’s
It was a Christmas book – containing many different stories/legends from the birth of Christ to the real Saint Nicholas to Christmas legends like the Christmas Spider
It was a large, oversized book, say 12″ x 18″ ish. It was not a thick book.

What was so great about it was the artwork – very beautiful renderings – not cartoony or modernish, more like realistic paintings. So the art was appealing for even adults, but the stories were short, maybe one or two per page. If I had to guess, I would say the art style was something similar to this picture below.

As a child, the images I remembered the most was the story of St. Nicholas paying the dowries of three poor women. They were all sleeping in a bed and he threw a bag of gold in through the window.
There was also a story of this flying ( but I don’t remember it with wings!), hairy, red-eyed beast with sharp tusks/teeth, but I can’t remember the story. LOL – I don’t think it was Krampus, because it was more like an animal (wolfish) than a human devil guy.
Another feature was the rich colors of the end papers. Like a renaissance fabric pattern. I think red with a little blue and gold in a repeating diamond pattern, I think – it has been a long time since the book was lost or given away.

So I know these are a lot of random details – I wish I had the title and publisher, but maybe you can help me – my desire is to purchase a replacement copy to pass on to future grandkids.
