This postcard has got the front caption all wrong.
It should say “In Awhile Crocodile”.
Florida’s alligators live in fresh water, the Everglades for instance. It’s crocodiles that are found on the coast as they like salt and brackish waters. Florida’s gators are famous, but most people don’t know that Florida has crocs too. Florida is the only place in the world that has both crocodiles and alligators in the wild.
So this poor kid, soon to be supper, is likely encountering one of Florida’s crocodiles.
