Pictures of both from early march in this blog (start halfway down):

(nice collection of photos that have me itching for another trip)
I was there in June and Seuss looked fine to me.
I do see the difference in donkey's teeth in the picture. (Can't tell anything about fading or cracking.) BUT, it's nothing that detracts from the sign or certainly not the park itself. I just assumed that's the way it was supposed to be.

Not that I spent time looking at signs and analyzing things, anyway. I was way too busy having fun! I don't think the Florida parks will ever deteriorate to the point where I would notice obvious flaws.
Maybe someone with a more critical eye can bring back some pictures to post
