In 1938, the Sky Bar Candy bar was first announced to the public by means of a dramatic skywriting advertising campaign. Sky Bar candy is a molded chocolate bar having four distinctly different centers en-robed in chocolate. Also known as the 7 up bar or 7-UP Bar. The four distinct flavors are fudge, caramel, peanut and vanilla nougat. Sky Bar still remains the only candy bar today to have four different flavors in the same bar -- A truly unique chocolate-y treat!
