It's the base to a sign that's no longer there, it was designed by WED and advertised it as the place to buy ticket books in the A-E ticket days. No ride connection at all, though I think it may be the last inside the park ticket location remaining.
AFAIK it spent over 1/4 century as a Kodak film booth (my memory is a bit hazy there - this may have been AmEx credit card signups).
