You can help protect endangered wildlife with your Valentine’s Day sweetie-grams: prettify your post with a Save Vanishing Species first class, semipostal, fundraising stamp depicting a magnificent Amur tiger cub. Net proceeds from the sale of these stamps support Multinational Species Conservation Funds, benefiting African and Asian elephants, great apes, rhinoceros, tigers, and marine turtles. You can purchase these sticky little lifesavers, created by artist Nancy Stahl, here.
