Zipper is a striking font designed in 1970 by Phillip Kelly for the Letraset dry transfer sheets and it shows itself as a true child of the 1970s. The most distinguishing characteristic is the markedly robust horizontal stroke, heavier by far than the verticals. In a line of text, the figures present a close, stripe-like line, strongly dominated by the horizontal. Zipper is meant exclusively as a headline font and should be used in larger point sizes to highlight its unique, eye-catching characteristics.
