vintage Christmas Card “Come All Ye Faithful"

vintage Christmas Card “Come All Ye Faithful". This beautiful unused Christmas card is likely from the 1960s (possibly the late 1950s) but there is no date on it anywhere. It is from a collection called Songs of Christmas. The cover of the box reads "The nicest way to send a thought. Songs of Christmas/ 21 Luxurious Parchment Folder Assortment/With words and music of the world's most beautiful Christmas carols and descriptions of their origin." This card features the Christmas carol "Come All Ye Faithful". The front of the card features the words and music of the first verse of this carol. The "sheet music" is surrounded by lovely artwork in an illuminated style. The top left of the card features a large O enveloping the new born King with Mary holding the newborn and Joseph standing and watching. The rest of the design surrounding the sheet music is made up of swirly green and fuschia vines and flowers. The design is rich with touches of metallic gold. A red border surrounds it all. Inside the card, the right side is an exact duplicate of the card front --except,instead of sheet music, there is a greeting in metallic gold that reads , “All good wishes for Christmas and Happiness throughout the coming year." There is room for a signature beneath it. The left inside of the card features the story of the the Christmas carol's origin. This card, as mentioned, is made of a crisp parchment paper. It measures just about 5x7 inches. It is in beautiful shape and has its own envelope
