A postcard on Funafala Lagoon side beach, Funafuti (Tafaatai o Funafala, Funafuti) in Tuvalu. This island nation is threaten by rising sea level. Thanks earthday_tuvalu, a group of Taiwanese volunteers, for giving out postcard in conjunction of the Earth Day.
A stamp commemorating 40th Anniversary of Earth day in 2010 with face value 50 cents was used to send this postcard. It was cancelled with its commemorative postmark but it is partially missing. This postcard was in transit vie Australia, as the Australian cancellation of NSW 2135 cancelled this stamp too, but the date is unclear.
