Hercules and the mermaids

No message, and the back of the card is kind of messed up, so I didn't scan. But the description reads:

HERCULES AND THE MERMAIDS
[Missing word] beautiful mermaids with a replica of Dynastes Hercules, the world's largest beetle towering over them at the entrance to the May Museum of the Tropics, Weeki Wachee Spring, Florida. 60 miles north of St. Petersburg on [?] S. Highway at Florida 50.
