Issued June 16th,1976. Around the time when this set + s.s. were issued,I stayed a few days in Ratnapura,the centre of gem-mining in Ceylon (Sri Lanka).The mines worked then very much so as the illustrations on the s.s.

I was half watching the History Channel on cable this morning while working on an article when I heard the words "the world's only cave Post Office". It caught my attention and I began seriously watching the episode "Underground Marvels, The Secret of the Rock". Wanting more information about the Postojna Cave in Slovenia, I looked up the cave on Google and found the following article: www.postojnska-jama.eu/en/wonderland-stories/the-worlds-only-cave-post-office/
The first Postojna Cave Post Office opened its doors in 1899, eighty years after discovering the most beautiful parts of the Postojna Cave in Slovenia. It opened its door to cave visitors in 1899, at a time when postcards were all the rage. The underground post office catered only to cave visitors and the guests at special events, the so-called Cave Holidays in the famous Dance Hall. Right on the edge of the Dance Hall, about 500 metres from the entrance to the cave, was a small stone post office (4 x 2 metres in size) with a door and a window opening, where visitors could buy and send postcards. Since Slovenia was at the time part of the Austro-Hungarian Empire, the post office was Austrian. Rob
PS I had no idea where to place this post, if Admin has a better category I'm on board.
