This was handed down to my family in a box of books that contained mostly stinkers. I saved it because the cover was squishy and it had seemingly decent illustrations.
But it's turning into one of my favorite anthologies to pull out for my kids at Christmas time. It has a nice range of Christmas stories, both classic ("Gift of the Magi") and less well known ("The Christmas Spiders"??). It has several slice-of-life descriptions of how Advent is celebrated in other countries (Ethiopia, Italy, Mexico, etc.). But I think my favorite part is that it has a selection of Christmas carols reproduced with actual music notation. My kids have favorites they want me to read every night, and these favorites have changed through the years.
TL,DR: I thought this book would be cheap trash, but it has been a lovely addition to my family's Christmas books. It will probably have something to offer my kids for several more years.
