This vintage  is "Bright Christmas Dreams" from 1987. It features a cardboard Crayola crayon box with four white plastic mice peeking out the top. The mice are sleeping under a red blanket with white polka dots and are made of plastic.

One of the mice is yawning and one is sucking his thumb. They wear stocking caps in red, yellow, green and blue. 

There is a loop at the top for hanging. The front reads "Crayola Crayons, Bright Christmas Dreams." The back is marked "1987 Hallmark Cards" and says "Christmas 1987" in the bar code.

There's some pen writing on the back of the ornament and the edges of the crayon box show a little wear, but it is otherwise in good vintage condition.
