Here's an example of some newer "jcp" era signage in the former Corinth JCPenney, where they had much more of the old-school stuff thankfully. There are way too many 'i's 'c's 'e's and 'n's in that word for me to ever get the spelling exactly right without help! Per Google though, they have apparently spelled it correctly in this case.
JCPenney, 1970-built(?), Cass St. near Hwy 72, Corinth MS
