Andrew Arbitell of Phoenixville, an advertising major at Temple, won a recent contest sponsored by Goldenberg's Peanut Chews to write a 10-word billboard slogan. He came up with "Enjoyed when the Rocky steps were just steps." Arbitell learned of the candy contest from Joe Glennon, his ad prof. The billboard is up on I-95 near the Peanut Chews factory through April 28. Besides the glory, Arbitell gets a year's supply of Peanut Chews, which will be delivered to Temple on April 11.
