I find it quite odd that there would be a celebration of the 60th year of relations as I am used to seeing 50th, 75th, and 100th. Why the Philippine Postal Service is so fond of the 60th anniversary of things is beyond me. I recall that there was also an issue in 2007 celebrating 60 years of France-Philippines relations, which according to a French stamp exchange partner went unnoticed in France. (Well, actually, I'm pretty sure it also went unnoticed here save for the few collectors and postal workers and French embassy affiliates in the country.) I also remember a 4v set and S/S celebrating the 60th year of the Bureau of Fisheries and Aquatic Resources. Strange, really.
Well, anyway, here are the issues from the Philippines-Korea issue, which I unexpectedly and coincidentally received on the same day (today).
Panagbenga is a Kankanaey term for "a season of blooming." It is also known as the Baguio Flower Festival, a homage to the beautiful flowers the city is famous for as well as a celebration of Baguio's re-establishment. Since February 1995, it has been held to help Baguio forget the 1990 earthquake that distressed much of the city.
