Moorea is one of the Society Islands, near Tahiti, and is part of French Polynesia. Frommer's travel guide once proclaimed Moorea the most beautiful island in the world. The sender of the postcard lives on Tahiti, but said she likes to go to Moorea for holidays or weekends. Thank you Magali!
The stamp, issued in 2010, is one of a set of 3 commemorating the 100th anniversary of phosphate mining in Makatea, one of the Tuamotu Archipelago portion of French Polynesia.
