The original mall's east anchor was Sears & Roebuck. Encompassing 150,000 square feet, the 2-level store included a freestanding Auto Center. Save for an updated nameplate, the store proper looks essentially the same today as it did in 1968.
Julius Garfinckel & Company had a 90,000 square foot store at the original MONTGOMERY MALL.
