Vintage 1939 white border postcard showing the 50 room Hotel Qui-Sana which was located at the southeast corner of Magnolia and Walnut Streets on the banks of the St. John's River in Green Cove Springs, Florida.

Built in 1907 around the natural Sulfur Spring, the hotel was renowned for its 78-degree mineral spring swimming pool, offering guests a unique therapeutic experience. Visitors also enjoyed amenities such as golf, tennis, boating, and fishing along the scenic St. John's River.  The hotel was demolished in 2002 and the current Green Cove Springs City Hall Building was built in its place. 

The card is a "Genuine Curteich-Chicago C.T. American Art" postcard, and it was printed in the USA.

The card is unused and in very good condition. It has a very light small dogear crease on the bottom right corner tip (see photos).
