Belgium, Earth Hour

From Essen in Belgium. One of the best machine cancels I've seen in a while. The stamp is from a sheet issued by bpost last year to commemorate Earth Hour.

This stamp is watermarked in a unique way. Under UV light, a power switch symbol can be (somewhat) seen in the middle of the Earth and the designers name and year are visible in the bottom right corner.
