Rare football tin sign was for this regional brand of soda from Miami (the regionality is what makes it so rare).  The bottle dominates the sign and the football player dominates the bottle.  Spectacular player with period dog-eared leather helmet tells us that "There's Life In Kik."  Obviously a precursor to "Jolt" soda, we bet "KIK" had a ton of caffeine, hence the brand name.  Some holes where it was hung up outside some backwoods general store, some edge rust but o/w EX.  Only specimen known.
