Germany Semi Postal Stamp - 1996

Below is a semi postal stamp of Germany on topic of "Preservation of Tropical Habitats" issued on July 18, 1996. There is a frog on the stamp, and I like frog stamps. This semi postal stamp contains not only image of frog but also bird, butterfly, insect, reptile, mammal, flower and a world map....... it has almost every thing for flora and fauna thematic collectors! This stamp really kills many birds with just one stone...... hehehehehehehe
