One 5.38 foot Teenage Mutant Ninja Turtles Banner. Banner letters measure 5 inches from top to bottom and are joined by metallic grommets that allow the banner to hang at an arc. Big letters with awesome action shots of the Ninja Turtles spell out "Happy Birthday" on our totally cool Teenage Mutant Ninja Turtles Banner. Hang your banner across the wall or the front of a table. Jazz things up a bit by tying latex balloons to either end, with long curling ribbons hanging down.
