St. Augustine, FLORIDA - Ponce de Leon Hotel:  The Ponce de Leon Hotel, also known as The Ponce, was an exclusive luxury hotel in St. Augustine, Florida, built by millionaire developer and Standard Oil co-founder Henry M. Flagler and completed in 1888. The hotel was designed in the Spanish Renaissance style as the first major project of the New York architecture firm Carrère & Hastings, which would go on to gain world renown.  The hotel was the first of its kind constructed entirely of poured concrete, using the local coquina stone as aggregate. The hotel was also one of the first buildings in the country wired for electricity from the onset, with the power being supplied by DC generators installed by Flagler's friend, Thomas Edison.  The original building and grounds of the hotel are today a part of Flagler College.   Novelty Co. of America.  The hotel was designed by the New York architecture firm of John Carrère and Thomas Hastings, as one of their first major projects.  Soon after, they would design the New York Public Library in Manhattan. Interior design of the hotel was headed by Louis Comfort Tiffany, and his company, Tiffany & Co, which provided the stained glass windows in the hotel's dining room. The hotel's furnishings were provided by Pottier & Stymus, a prominent New York City furniture and design firm at the time. Bernard Maybeck, whose later designs include the Palace of Fine Arts in San Francisco, served as a draftsman on the project and designed its 540 guest rooms.  This Undivided Back Era (1901-07) postcard is in good condition, but shows some edge wear.
