Probably more like '62 or '63---Penney's didn't really roll out full-line stores until then...it's kind of a good story about how in 1957 a really forward-looking executive said "we've got to be in the mall" and went forward to go in virtually every mall built from 1960-1970, using the profits from the small town stores to build them, and in 1962 or so to buy the catalog business (which they bought already computerized....hence why it has survived...no "old-time" legacy problems like Sears/Wards)
