Hong Kong Biodiversity

My scanner makes this cover from Hong Kong look like a plain brown envelope but it's actually shinny gold in colour. Very nice. The stamp sheet is the second biodiversity issue from Hong Kong post issued in July of 2026. These stamps feature flora and fauna through the seasons. From left to right: spring featuring the South China Rhododendron and Red Helen butterfly, summer showing a Hong Kong Clubtail dragonfly and Hong Kong Freshwater Crabs, autumn featuring the Yellow-breasted Bunting and winter featuring the Blue-spotted Crow butterfly and Chestnut Tiger butterfly.

This postmark is, I believe, a Central Mail Center handstamp. And the "Big Buddha" stamp at the bottom left I'm guessing was applied at the site of the 34m tall Tian Tan Buddha on Hong Kong's Lantau Island.
