I thought it was called Clarks. I was there once and remember thumbing through a Mad paperback magazine, that was the first time I had seen Mad, I don't remember if I was reading at that time but I liked what I saw. Some relatives lived in that part of town and the smell from the stockyards was very unpleasant.
Spartans does ring a bell, I never would have remembered it. I was there just once I think, with my mom and sisters. On that same day we shopped there I remember hearing the new Byrds song "Turn Turn Turn" on the radio, it was released in 1965.
I attended the grand opening I was very young it must have been around 1963-64. The Wilburn Brothers and Johnny Weissmuller were there. The stores I remember were Montgomery Ward, Firestone, Ashburn's Ice Cream (I think it was called) and Panchos which opened a little later I think. There was a discount store across from Panchos but I don't remember it's name. I remember looking at the new Beatles LP Revolver there.
