On the copyright offices site theres a search function. I can't find anything at all under Jasper Ewing, and the oldest dated copyright found by searching for "LSU football" is 1950. so there probably wasn't a renewal.
You'd have to do a bit more searching to be 100% sure, but so far it looks like you're ok as far as reproducing it goes.

Older stuff can be researched in person, or they'll do it for you for $165/hour.
If you ever get to DC it might be worth a trip through the catalog to get the whole copyright history.
