The Florida Collection is an online resource made available by the Jacksonville Public Library. It includes biographical sketches, historic photographs, and old postcards, among other things. Browsing through the postcard index, I discovered:
* a 1900s photograph of horses at the starting line at Moncrief Park
* two brave men plucking feathers from an ostrich, and
* a 1940s advertisement for Berney's Restaurant.
The Berney's card proclaims "Dine with the Man in Green from Ripley's 'Believe it or Not'." And sure enough, there's a man in a green suit. A little googling finds a January 18, 1937, letter to the editor, published in Time magazine: "Dressed completely in green day and night, he will give to any woman dressed entirely in green the choice of his menu, gratis. ... The only man in Florida to drive an automobile with a green licenses, he has even painted the 'White Horse' Scotch whisky statue green."
