“Missing You” portrays a bird, the White-eyed River Martin, which shows how delicate and fertile our environment in Thailand is; however, it may now be extinct. No one has ever seen this kind of bird since 1969.  

As a Thai endemic, this bird was featured on a 75-satang postage stamp in 1974 as one of a set of four depicting Thai birds and on a 1974 5,000-baht conservation issue gold coin. 

The form of the bird in “Missing You” came from this 75-satang postage stamp in 1975.

The window glass was covered with transparent stickers, which overlapped atmospheric light colors. The form of a flying bird was left out as an empty space.

The large swallow or White-eyed River Martin (Pseudochelidon sirintarae), whose scientific name commemorates Princess Sirindhorn Thepratanasuda, was found wintering at a lake in central Thailand, but its breeding grounds are unknown.

The bird was founded by an eminent Thai ornithologist and mammalogist, Kitti Thonglongya, in 1969.
